According to my LHS, the largest container of thinner available from Testors/Floquil is now only a halfpint can, at (of course) a not-exactly-halfpint price. The stuff's been expensive all along, but now with only small containers available, the problem has increased, and I'm ready to entertain a good substitute.
Is there a garden-variety product on the market that serves as a good mixer with Floquil solvent-based paints?
Thanks in advance for any informaton.

Since the DioSol is now almost imposible to find, I use what I still have on hand to thin for airbrushing only. Any regular quality paint thinner works of clean up and brush painting. The new version of the Floequil thinner is not the same. I used to paint one shot over bare plastic using Diosol as thinner and never had any problems. The new thinner will craize the plastic on many models if you don't prime or barrier first.
I had a chemist do a quick analysis of the DioSol and it came back about 80% toululene 10- 15% Xylene plus other. I have tried straight toululene and it works, but will dry very, very fast. It is hard to not get a rough, gravel finish when this happens. You need to apply more paint and shoot much closer to the model than I'm comfortable with.
If anyone has found a better substitute I would like to know also.

I've always used lacquer thinner to clean my airbrushes and paint brushes. While I still have some Diosol (2 pint cans), I'll probably use the lacquer thinner when I run out. It will dissolve/thin almost anything. I use it to clean my airbrush after using acrylic paint that always hardens around the inside of the color cup.

Floquil's Diosol is a mixture of two common thinners, Xylol, and Toluol (tolulene). These can be had by the gallon at any hardware/paint store for not much more than the price of the pint/half pint.
Either one on its own also will thin floquil, scalecoat I & II, any enamel based paint so you do not have to buy them both and mix your own.
Scalecoat's thinner is also a mixture of the same two main ingredients, although in different ratios.

For the last few years, I found that lacquer thinner works great for thinning Floquil.
Years ago, Floquil colors could be mixed with each other, thinned with their own thinner, and kept, ready to spraying, for years. (Quite a few years ago. I still have some paint in their square bottles.)
In recent years the formulation must have changed as a spray mixture often becomes gummy in just a few weeks or months. I assume they are trying to make the fumes less toxic.
So now I use lacquer thinner and mix only what I will use in a couple days. After spraying, lacquer thinner does a very good job of cleaning the airbrush, followed by spraying a quarter ounce of a 50/50 ammonia - distilled water mix ,then a quarter ounce of straight distilled water.

Floquil was bought out by Testors several years ago, but the formula starting changing long before that. First the EPA, (and I think the FDA both), dictated that all lead had to be removed from all paints. This effected every paint maker in the country/world that sold paint in the US. Some things this caused was loss of shelf life, as lead also served to keep the pigments from coagulating in the bottles over long periods, as well as surface durability. Some older paints such as Scalecoat, lost much of their well touted ability to take damage without chipping or flaking. The next change in Floquil came when they started converting their lacquer based formula over to enamel. This is when the "black" label Floquil became the "red" label paint we have today.

I don't paint real cars, so it doesn't matter to me. I doubt if they even use enamel these days, more modern fast drying high techpaints are used.
I use lacquer thinner because it works.
I would use Xylene found in Home Depot or Lowes. Toluene is a suspected carcinogen and I would stay clear of it. Even with Xylene, use a spray box and wear a respirator. These hydrocarbons are not good for you if inhaled. I would be surprised if there will be any organic solvent based paint on the market a few years from now. There are just too many liability issues associated with them.

Now, I am referring to the red label stuff:
I did not use a chemist, I used my nose. The Floquil paint smells like mineral spirits. I thin Floquil with mineral spirits for spraying and use mineral spirits for clean up.
Not being a chemist and reading this thread, I am surprised at my success. Makes me want to try alcohol to see what happens….

Sorry it took so long, but now that the firefighters have left… Just kidding, but no joy. I’m back to ($1.89 a quart) mineral spirits.

Funny you should mention it...I did that all the time.
My full size race cars are all painted with single stage enamel. My short track car got banged up pretty often, I spray the straightened panels with the same enamel thinned with laquer thinner. Turned out fine, and it sure dried fast!
On the other hand, one time I painted my road race car with industrial enamel. The label on the paint can said use mineral spirits. Well, we had no mineral spirits, so we used enamel reducer. We missed 2 races, because the paint would not dry! It was 3 weeks before we could put the car back together!
Painted the trailer using the same paint, using the mineral spirits, and it dried in about a half hour.
Moral of the story, be careful using thinners not recommended for the paint.

Wow, your nose is out of whack. Dio-Sol smells nothing like mineral spirits, but a lot more like lacquer thinner, which is a combination of xylene and toluline.
According to the MSDS on Dio-Sol it's 40-45% VM&P Naphtha, 5-10% Xylene, 1-5% Ethyl Benzene, 5-10% Aromatic Hydrocarbon Solvent, and 40-45% Light Aromatic Hydrocarbon.
Since I'm not painting huge areas with Floquil, a 16 oz can of Dio-Sol lasts me several years. I use it only for thinning the paint to spray, and clean up with lacquer thinner.
All these components come under the warnings of "good ventilation" and "air purifying or air supplying respirator." These can be dangerous chemicals if not used with the proper caution.
Let me try again.
The question was is there a cheaper and more available thinner for Floquil. I gave an answer: Mineral Spirits. I stumbled upon this old thread looking for answers about other thinners and had an answer to give so took the time to write the post and share my experience.
I know what the Floquil paint smells like-- it smells like paste wax and paste wax contains mineral spirits to soften the wax, which led me to try mineral spirits as a thinner and it worked perfectly.

My nose is out of whack? You sound like my ex-wife. I am sure you are very proud of your nose, and see that it is accustomed to being upturned, but leave mine out of it because, besides its being “out of whack,” it can also get out of joint. That is, if you respond to one of my posts, do so with respect.
A friend of mine that does a lot of airbrushing uses lacquer thinner.

I was going to stay out of this, but I feel that some additonal info might clear up a few disagreements here.
I teach automotive collision repair and can attest to the fact that Enamel based paint refinishing systems (Single Stage Acrylic Enamel, Single Stage Urethane Enamel, and Enamel Basecoat/Clearcoats) are still used EXTENSIVELY in the United States. These products have undergone "high-tech" changes over the past 2 decades. DuPont, PPG, and BASF are the dominant "top guns" in this arena. Catalyzed Urethanes and Polyurethanes are tough, but quite expensive. Single Stage Polyurethanes Enamels are usually preferred for commercial transportation fleets because of their high durability properties. This is often the choice of rail, trucking, aviation, and marine companies. The prototype Santa Fe F units that were repainted a few years back were refinished in Polyurethane.
Waterborne Enamels are increasing in popularity, but not dominant yet, except in California. GM's Saturns are factory finished in Waterbased enamels.
Lacquer based automotive products are still available but are not as popular as in the past due to inferior durability. An exception would be the House of Kolor lines owned by Valspar which include beautiful quality lacquer based products (enamel as well) used in custom paint refinishing. Very, very expensive.
For the issue of thinning the solvent based Floquil:
I have found that Automotive Paint Lacquer thinner works just fine. The paint cures to a tough, durable finish. Wet sanding and adding multiple colors is a cake walk. The "Mineral spirits lacquer thinner", works in many cases but can be more of a hit or miss shot as far as adhesion and durability.
Metaphorically:
Mineral Spirits = Ford Escort.
Automotive Lacquer Thinner = Ford Boss 302 Mustang.
For those of you that have been using Automotive Enamel reducers in lacquer based paints, that is also a "hit or miss" russian-roulette game that can work, but why risk it? Generally, automotive lacquer thinner is cheaper than automotive enamel reducer.
BTW: Enamel products may be sprayed over freshly cured lacquers, HOWEVER, spraying lacquer material over freshly applied or freshly cured enamels can wind up destroying the enamel finish. Been there done that.
Automotive Lacquer thinners in varying grade qualities are usually sold in 1 gallon, 5 gallon, and 55 gallon containers. Wash lacquer thinner, used to clean spray guns, is cheaper and works well with Floquil and even Scale Coat II.
Guys, Have you all forgotten Scale Coat II Thinner? Also a good product that you can still acquire in 1/2 pint cans. Should be enought for a good number of HO scale paint jobs.
I use mostly acrylics now and utilize solvent based paints for metalizing. After using the above mentioned products for 20+ years, I always recommend using acrylic based paints in scale model work whenever possible.
"I like my Pullman Standards & Budds in Stainless Steel flavors, thank you!"
Testors did change the formula of the Floquil line a few years back to meet with updated government VOC and Haz-Mat standards. I certainly would like to see an MSDS sheet on its composition. However, just my opinion, it's apparently lacquer based, not enamel.

Hi!
If you do a lot of painting, I would check out some of the alternatives offered up in previous postings. But if you don't paint all that much, I would stick with the Floquil.
All that being said, Please remember that ALL of the various thinners are very dangerous - either to breathe, to ignite, or to ruin stuff that it touches. Please take this seriously!!!!

Antonio, what do use to thin acrylics? Just curious.
My friend who paints uses Xylene to thin Floquil paint (yes, he has a paint booth), so I tried it, but I really dislike using Xylene and would like to shift over to acrylics and water-based paints.

Hi,
Distilled water when I use Polly Scale. Results have been very good, so far.
According to the Testors website, their "Universal Enamel Thinner" has replaced all sizes of Floquil Diosol and Model Master thinners.
http://www.testors.com/catalog_item.asp?itemNbr=2818
I have tried the alternate Floquil thinner someone mentioned above; it sucks. I tried it, and the paint would not flow on the plastic or primed surface, it beaded. I will use it to clean the airbrush and paint brushes until it is gone, then forget it existed. For the time being, I am using the new red can universal stuff to thin Floquil and Model Master. I have not had a problem with it.

I also use regular laquer thinner and have had good results. I sure beats the heck out of paying ten times more money for Floquil's so-called "special" (aka overpriced) thinner.

The MSDS I have for DioSol is dated 2005. The formula listed on the MSDS is repeated in my previous post. It's definately still a HAZMAT.
One other difference not mentioned between lacquer thinner and mineral spirits is the evaporation (drying) time. Lacquer thinner evaporates faster.
