metal
plastic
even acrylic

what are the best primers for that particular material? i know primers come in different types for different metals....wood....plastic...metal...i ran into interesting problems painting model rocket paper tubes with wrong primers long time ago and even back when i was 8 we had issues with primers on the pine wood derby cars...etc.

so fo rthe material...what have you found to be the best type?
also...budget brands that will get 'er done?

buget brands will do, but be careful, primer only, get good paint

plasti-kote make a wide range of paints ideal for painting pc cases...

primers, vinyl-dyes, uv paints...

thanks....got an idea for my $25 white case that i think is about to go a shiny graphite
ive just seen material specific primers and thought id ask whose found the good stuff for that. ive got some metal primer that should work nicely..(red/brown rust colored)..

Just go with a good primer. your going to have to sand and sand anyway. Plasticote is ok but try krylon.
