    question on painting engine

    anyone have an idea on exactly when or how I would go about painting the engine?

    after looking at some pix it would seem engines are painted after they are put back together...do I cover the open ports with cardboard or something?

    just looking for some tips here.

    I paint after the engine is together. I made alum. caps for the exhaust and intake (reed flange) for pressure checking and painting. Cardboard will work well for painting. I cleaned then scuffed the entire engine with scotch bright pads, then taped all the nuts, bolt heads, and seal to prep. for painting. I painted the exhaust mani, pipe, and bed plate separately.
    I used Dupli Color DE1621 Old Ford blue on mine.

    thanks for the tips...did you clean the engine after scuffing it up but before painting? I would assume it woulud need some degreasing of some kind wouldn't it?

    Thinner would do the trick. Just wipe it down with a lint-free cloth, not a shop rag.

    After I scuff the items, I use compressed air to blow them off, then use a tack cloth with paint thinner to wipe it down. Then paint.

    Truth be known, it should be cleaned before and after sanding/scuffing. If you don't clean it first you run the risk of grinding the dirt/grease/oil into the surface. Not a big deal if you're just useing spray paint on an engine but if you ever paint anything like a hull or car it's a must do step.
