Painting Engine block

Okay, I just got my block back from the machine shop, baked, magna fluxed, bead blasted, bored out 40 over, crankshaft alignment, freeze plugs and camshaft bearing pressed in. I am now ready to paint the engine block. I was wondering if anyone had any good ideas on prepping the engine for paint and what type of paint to use.

Clean with a degreaser simple green or something similar. Mask off what you don't want painted. Auto parts stores have a specific spray paint for engines in many colors. Have some fun be creative with the colors. I went black no problems two coats. I also used an aluminum color on the intake trans and transfer case.

Engine enamel comes in everything from rattlecan to a professional two stage setup for use in a gun.

DO NOT USE SIMPLE GREEN to degrease just before painting. It will leave a residue that can allow your paint to bubble and peel. Go to a professional paint supply and buy a can of prep degreaser and cheesecloth. OR go to home depot and buy a can of MEK Substitute and lint-free microfiber cloths and wet the cloths with the MEK and wipe down your surface prior to painting. Let it dry completely before you start painting. I highly recommend using a "Direct to metal" primer or Self Etching Primer on any surface prior to rattle canning it.

80% of any paint jobs longevity is determined by the prep work. Don't skimp on the prep or you'll pay the price later.
