Re: Engine primer and paint
Or Duplicolor. Paint isn't the problem... it's prep of the the surfaces to be painted.

Re: Engine primer and paint
I've never used primer and generally use Dupli-color. Alcohol or lacquer thinner prep well. I've used break Clean to degrease and painted straight after that. I'm sure there are more professional ways. But I'm not talking show quality,just simple and easy

Yes you will need an engine heat rated primer. They are right along side the engine paints in the parts stores. I don't use a primer either. I usually do about 4 to 5 coats f paint. Gary

Re: Engine primer and paint
In Tucson, I take advantage of the Sun, and leave the part out in full sunshine to warm up, before shooting paint. I also shoot the surfaces down with Brake Cleaner, but let it evaporate completely [and the part to warm back up] before painting. I have tried it with hi temp primer and without and can't say one is better than the other. VHT is a division of Dupli-Color now, but that high heat range is better on headers and exhaust manifolds. Hi Temp [+500*F] Dupli-Color is OK.
If you're not shooting on bare metal, scuff the surface wth steel wool.

Re: Engine primer and paint
I shot several engines with epoxy primer then base coat/clear coat.
They still look pretty.

Re: Engine primer and paint
I've had good results with PPG epoxy primer and VHT spray.

Re: Engine primer and paint
If you're not looking for a glass smooth surface, primer isn't really needed. I've only used primer once on an intake manifold and it didn't make a difference what-so-ever. Save your time and money. And I use the Dupli-color engine enamel too. On a driveable vehicle, I'll take it to a local quarter car wash, spray it with engine degreaser, use a scraper for large particles then wash it off and let it dry. Before I paint it, I'll use brake cleaner for the residue and just paint it.
If you have peeling/chipping paint, you'll want to scrape that off or your new paint will still come off.

Re: Engine primer and paint
Resprayed this engine last weekend after cleaning in Purple Power, brake cleaner, and a bristle brush. Local machine shop bead blasted the oil pan, valve covers and timing cover for a very reasonable price and it was totally worth it; I literally sprayed them down in brake cleaner to degrease the finger prints then shot the orange.
Dupli-Color low gloss black, VHT Chevy orange, and (uncured) VHT header paint on the manifolds. Previously all of the engine was in Dupli-color Chevy orange, which held up pretty darn well over the last 15 years. |

Re: Engine primer and paint
Prep prep prep.
Ground everything down till It was smooth, clean, then spray bombed it. I've seen worse in $100k street rods.
