The key to painting engines? Keep the material as thin as possible. (And very good prep work). This means it's probably a lot better of an idea to de-burr and metal finish everything, rather than using any filler or primer. It's a lot of work, but the whole point is to show you the 'right' way. Also, I like regular epoxy sealer and regular base coat/clear coat (or matte). #paint #engines #matte #satin #deburring #work #lotsofwork #metalfinish #handfile #file #quality #details #fitandfinish #tylerkrauseinc
