I personally have not painted any engines with BaseCoat/Clear so I can't
honestly say..........But I did paint one engine with Acrylic Enamel........
NO Reducer - NO Additives - NO Primer....straight out of the can.
The block was (acid bath) clean and I applied the color (76 Corvette Yellow) with a
brush...(2 coats). The paint held up extremely well. The only place the paint
failed was at the heat riser areas on the cast iron intake, It burned off.
The rough texture of the block and heads practically hid all the brush strokes.
Remember the block and heads don't get "that hot" as compared to Exhaust
Manifolds and Headers ..... the main thing to be concerned about is how "clean"
the parts are. If the engine is in the process of being overhauled I would
recommend painting the parts right after the machine work and a good acid
bath before any assembly is done. If the paint is applied and cured properly
cleaning any spilled oil off of it will not be a problem. But cleaning a greasy
engine so paint will stick can be.
JMHO....others may vary.
