Welcome back! I have painted several engines and a few cars, besides weathering all of my locos and cars. In my experience, Floquil is still the best choice. I have never used "barrier" primer for plastic they offer or Dullcoat (until after decals were applied). I spray the first coat on quickly and lightly and have had no problem with scoring of plastic. Too thick an application would be a problem, however. After the first, light coat of paint has dried (when the odor is gone), it has been my experience that the plastic is safe for Floquil. I have two single-action and one double action airbrushes but strongly prefer the single-action brush for such work. One "thick" spray with a double-action brush can spell disaster on a shell. You are right--I have tried acrylic thinner, denatured alcohol, distilled water, etc. but clogging is always an issue, not to mention the difficulty of cleaning the airbrush if the paint dries in the brush (doesn't take long!). Floquil Barrier may be a good choice if you have doubts about plastic scoring.

Welcome Back!
Usually Dullcote is sprayed on 'after' you have painted the model to 'flatten' the gloss finish. Scalecoat and Floquil both have plastic prep products to protect plastic. Floquil has a Polly Scale line of acrylic paints. This is NOT the same as the old Polly S line you might remember.

It's been awhile since I have done any painting but I use FLoquil. They now make a special material called Barrier that you can spray on before painting but I have found that keeping the paint almost dry when applying the base coat will result in no plastic damage. If you haven't painted in 30 years I would suggest you have a learning curve regardless of material and the switch to non solvent base paint is probably a good idea. Spraying with acrylics is not difficult and you can use rubbing alcohol to thin it so it evaporates easily upon spraying
I prefer Solvent Based Paints to Acrylic. Since Floquil has changed to an Enamel based finish, I now use Scalecoat II paints for painting plastic. Scalecoat II is especially formulated for painting plastics versus the standard Scalecoat Paint. The major advantages of Scalecoat II is a primer is not needed on the model and the paint dries to a gloss finish right out of the bottle.
Last night, I painted 5 boxcars in Boxcar Red in less than half an hour. Normally it would have taken an hour and a half. I did not need a primer coat, nor a gloss finish coat for decals, and the paint went on and covered all the nooks and crannies easily as compared to Floquil.
I would look into using Scalecoat II, but use a spray booth due to the fumes. I have stopped using Floquil entirely.

Surian PathI used to deal with model shop out of Lansdale, PA.
Hmmmmmmmm, this product sounds interesting. Do you happen to remember which shop it was? The Lansdale shops today are Penn Valley and Lins Junction. Combined with Lins Junction is a place that deals with large scale, Hennings. Any of those places sound familiar?
Surian PathRick: Sorry my reply is so long getting back to you. I had to go out of town for several weeks, but when I got back I started checking local hobby shops for Scalecoat II. No luck. Only one hobby shop had Scalecoat I. Looks like Walthers may be the only source for me. The San Diego area just doesn't have it. ...
David,
I assume you live in the San Diego metro area? Have you tried Reed's Hobbies in La Mesa? I live in El Centro, and frequent Reed's when I'm in the area. I recently bought some Floquil and ModelFlex (probably my last bottle of that crap, but that's another thread ...) from them. I'm pretty sure they had Scalecoat I and II as well. If not, I'm sure they could order it for you.

If you want you can order Scalecoat directly from the manufacturer, Weaver Models. Web site is http://www.weavermodels.com/page11.html

I prefer Scalecoat 2 for plastic but I use a primer. Tried the no primer route and it took too much paint to cover the black plastic. I use either Floquil grey primer of Scalecoat 2 MofW Grey as a primer followed by the colour of choice. Allow several days for the primer to completely dry before painting.
Scalecoat 2 and Floquil don't mix when applying Floquil over Scalecoat 2.
Unfortunately, thinner based paints are probably on their way out, largely due to health / environmental concerns. Acrylics as noted can be a beast on a good internal-mix airbrush, I tend to just use a cheapo external mix Testor's airbrush for acrylics just because it can't get gummed up like my expensive (and now worthless) internal-mix airbrushes did.
Actually, whenever possible, I use Tamiya spray can paint now. It's not like the old style spray can paints, it goes in a nice smooth layer and it's pretty easy to get a result comparable to airbrushing.
