Opinions on engine paint

What brands of engine paint have you used? Likes or dislikes?

I've used plasticote and duplicolor recently.
The plasticote seems to work good but has to be recoated within a few hours or it will orange peel.
duplicolor seems to work better and sprays a finer finish. Recoat times don't matter. Very high gloss.

What Dupli-color did you use?? Was it the VHT enamel?

Biggest problem I've had with engine paints is rust bleed thru. I started painting with rustoleum and the a coat of correct color after that.

The duplicolor is called engine enamel ceramic. It says:"Dyno heat tested"

Rustoleum has come out with a line of engine paint. I saw it advertised in car craft or hot rod. I haven't seen it in a store or on-line yet.

all the plasticote i've used on motors has flaked off in giant pieces, the duplicolor hasnt had any issues.

I just used 3 coats of tremclad on the block and stove black(for woodstoves) on the turbo and exh manyfolds.
After now a yr it seems to hold up well without flaking or peeling.
As with any paint job, preparation is the key.

Bill Hirsch engine enamels last for years. My experience has been nothing compares to it, not even close. Available in aerosol or quart cans, I like the quarts better. You can even brush it on and it flows out nice. Check it out.
Search on the name to find the website, I don't know if I'm allowed to post it.

Curious on the best methods to prep turbo and exhaust manifolds? I would like to paint mine on my new build.

Abrasive blasting is gonna be the best to remove all the corrosion & leave the surface with a nice "tooth". Pull the turbine housing off the turbo, then abrasive blast both the turbine housing & exh manifolds.

Be diligent to ensure all blast media is cleaned out before reassembly. Yes, it seems obvious but I've heard of both residual blast media & even leftover extrude hone media doing damage to engines at first startup.

Glass bead blasting does a very nice job of making oxidized cast aluminum components like compressor housings, intake manifold & hat, look new again.

If porous castings (both cast iron & aluminum) have oil/grease soaked into them, it's best to clean well with solvent, make sure the solvent's evaporated away, then bake out any oil remaining in the pores - same prep for pre-powder coating. You don't want that stuff trying to volatize out of the part (thru the powder coat) when it's in the cure oven.

Dieselslug, back in the early stages of his engine buildup, said he used stuff from Eastwood. IIRC it worked well for him, so this was the stuff I was going to use in my engine buildup... Though it would be best for him to chime in on this since HE used it:rolleyes5:

I soaked the exh manifolds and cast iron turbo parts in diluted muriatic acid and wirebrushed the piss out of it,then pressure washed it, it came out clean as new.

I'd check with Eastwood they have many painting systems to choose from www.eastwood.com

 

[Alexe]

Eastwood is excellent, this is worth checking out.

I painted my '50 Chevy engine in 1987 with his paint and it is still good.
No peeling or flaking.
