Arghh whats it doing?

[farmernick06]

Hello all again ... i've just painted up my New Ray combine into Claas colours ( Rover applejack green from Halfords ) but as soon as i sprayed it on after a few seconds it appeared to start to crack  \ I have primed it and i've just put on a second coat to the same problem  \ Can anyone tell me why and how i can resolve the problem?

No I didn't. I said that they were 1/50 scale that I could get, but I can get 1/32 Mega and Claas decals

Oh yeah sorry mate got mixed up ... like usual

room temp plays a large factor also, if its cold the paint dosnt take properly and the gloss appears dull

now know why some paint reacted, didnt leave an hour between undercoat and gloss

sometimes better to take the shine of the plastic with a fine emery paper. gives a better base for the paint to stick to.

Don't use a cellulose based primer or paint on plastic or it will melt, you won't drool over your tractor, your tractor will drool over you!
