RE: Paint compatibility help please!!
I have no clue what the base chemistry of these paints is... there are no words on the cans to give a clue. Eash had a bunch of nasty sounding chems listed on the back, leading me to think it's not latex. Reversing the order could certainly work, only problem is that I already had two colors down following the old light to dark routine. Maybe would have worked though.
I've had great luck with PPG clears over latex, rusto, perfect paint, testors, krylon, waterslides (really light coats!!), decals, etc.... just about anything. I might use some Nelson flat clear that I also have laying around; being water based this should really be a non issue ( I hope)
