Scratch-brush weathering

[Anonymous]

I’ve got some wood freight cars I’m working on and I would like to try using the “scratch-brush” weathering technique on them. Has anyone used this method with Floquil paints? The Star brand paints advocate using this technique, but I must order the paints and the thinner that goes with it. Both paints are lacquer based, but I don’t know if the Star brand has different qualities that allow the “scratch-brush” weathering.

Never heard of "scratch-brush" weathering--what is it?

It's when you get itchy when brush painting! [:D]

Seriously folks, it's using a scratch brush like this one:

to scratch away a top layer of paint to simulate weathered paint on a model. I got one a while ago but haven't done anything that would require it yet.

I've used it successfully with several types of paint including Pollyscale and Badger Modelflex. I really don't think it matters on the type of paint you use.

I use a stiff fiberglass pencil for scratching back rather than the metal one shown in Bob's link, they are less aggressive and allows you to build up the scratching rather than taking so much paint off at once.

I usually stain the wood with black/brown acrylic inks before painting.

I've been wanting to pick one of those up and try it for weathering myself.

One effect I like on the wooden freight cars (since they're old in my almost 1970 era modeling) is to spray GlossCote on the wood carsides, and when it's dry, overspray with alcohol. It makes the wood look older and greyer. Just remember to scratch brush, or whatever your fading technique is, the herald and weathering first. If you don't do it first, you will end up with an old, weathered looking wood car that has nice, new looking heralds and lettering! As they say, ask me how I know this!

I was able to salvage the appearance of the car, barely. And it didn't look as good as it did when I sprayed the initial coats of DullCote and alcohol.

Lionel Strang just had an article about scratch brush weathering last fall in MR. Can't recall the issue but presumably is Oct, Nov or Dec.
He uses Bradgon adhesive weathering powders after scratching the side of a car
The brush is fine bristles of metal (steel or brass) that dulls the finish.
