Whoa - nasty
I've never had that problem before............one thing I've had a lot of success with in washes is paint the cockpit interior color, give it a quick squirt with Future, then use oil or enamels as a wash, and you can use thinners to wipe off any excess paint - the thinners won't affect the future, then a flat overcoat and a drybrush.
Might seem to be a lot of jerking around, but I've had very few disasters and some very good results using this method - and gee do I hate doing things twice.
Just make sure that whatever wash you use is a different type of paint system than the original coat of paint so that the wash doesn't soften the original paint.
