Tkanks for the input guys. Pretty much confrmed what I thought would work.
I'm posting a few pics of my project ,so you can see why I want this right,
A modeler for 40plus years , I"ve gotten back to mainly WWII warbirds past few years , but have lots of time with scale street rods, customs and circle track racers over the years.
I've used bottles of auto touch up paint many times, using auto sanding primer as a base sealer. Works great sealing off red or yellow plastic before paint.
Currently closing up the bottom with the oil cooler/radiator inlets and exhaust. ALready a couple coats of sanding primer.
My final caots of prime will be the filler sanding primer to take care of small scatches. ( I want this beast smooth, it's a 500 MPH racer).
Found some great hot rod colors at Walgreens. Sinful Colors?,is the name . Very wild colors to fit the name Tantrum.
Lady looked at me crazy when I explained what I was looking for. May take a look into nail decals too.
BTW A couple pics of auto touch paint I've used over the years.
