Wilson, Ditto phatbob's tip on paint from Home Depot, or Lowes for that matter. I had em mix up both colors for mine. Didn't go with the clear, as mine was electric, and I liked the flat finish better. Thin the paint down with water or washer fluid and you can spray it out of an HVLP or even an airbrush.

As for the decals, I'd just sand the areas the decals cover, and respray. Lot easier then trying to remove em and taking the chance of damaging the covering.
Something I found on a couple of the NitroPlanes/CMP birds that have a painted finish over covering. Often the covering under the paint is a completly different color. Like they used what ever they had laying around to cover the bird, then sprayed it.

My 120 scale P47 had dark brown covering, under the light green paint job.


Really liked this bird, (Corsair)I built my own retracts, even the tailwheel, and modded all the flight controls A/E/R, to internals so no draggy control horns.
