Hi, So I was wondering what the best clear coat is for models, I paint some 3d prints that get used rather than just being to look at and the paint can rub off in places. So is there a clear coat I should use for these? Should I be looking at 2-part or just buying a rattle can? Should I be buying a cheap airbrush to run it through or is it ok in a regular airbrush? Thanks for any reccomendations.
