Showing an under coat of paint

great tips guys! I'll be trying these out on some styrene or an old model. Thanks guys!!!

i got the same mountain to climb rebel, and i'll tell ya how i plan to do it, though i'm not real sure its gonna work, but i love tryin' new stuff. all you gotta do is repaint and start over if it don't work. anyway, i'm gonna "scrub" off some invasion stripes to try and recreate the look on the real paint job on a certain subject i'm workin' on. here is how i plan to do it. spray the base color, let it cure, and spray it with either future or a flat coat, something to separate it from the next coat of paint. then, when this is dried, i plan to take the "Swanny Sander"(this tool can be made by following the directions on Swannysmodels.com. anyway, i'm gonna attach a super fine grit of sand paper to my Swanny sander and "rub" it off. maybe this will work for you as well. i'm gonna try it soon. later.

If the red is enamel (or any model paint that is not acrylic), and the gray is acrylic, it is pretty easy to control how you rub an acrylic top coat off if you do it not long after you paint the gray on. That can be done with almost anything like a pencil eraser, and you'll probably have to keep what you're working on damp with water. Instead of water, alcohol will make it go faster. If you want a nicer tool for the job, get something called a "Colour Shaper" from an art store. They come in different shapes & sizes. Some of 'em have little wedges to help dig under a layer of paint.

that looks like it would work fine for ya... I was thinking of the salt weathering technique but that may be a bit stark for what you are trying to accomplish...
