I used goof off and lacquer thinner, but I didn't completely strip it, just the heavier parts where the factory paint was on there really thick and obscured the detail. I had to completely strip the R2 unit though, and I used lacquer thinner with an old toothbrush.
I use Plastikote black under plastikote white. 2 coats of black, one coat of white, it makes a nice light gray with a slight wash affect.
I'm starting the weathering.
Where do you get your Plastikote these days?
The primer is laquer based, yes. Dries QUICKLY.
