Duplicolor Cast Iron engine paint

[HOTT]

Some people paint, then take the bolts out one at a time, clean them, then reinstall. You can also use 'liquid mask' (not sure of a brand name) that you can dab on before painting, then remove when done. I don't know of any less tedious way, but others might!

I like to remove one at a time and clean with laquer thinner, then 2-part clear the whole motor.
It's the only way to get that "installed after assembled" look. It won't take you
anymore time and you won't find and accidental dot later.

Its a little late but

I will be painting the new (1100) engine before I put it in so I'll take pics of it out of the frame this time.

I use the same paint for Eccles' engine The colour is more golden in good light...


I just leave most of the bolts painted to match; After all, Honda used bolts that were more or less the same colour as they painted the engine and it will help protect them from corrosion a bit. For chromed ones I remove them and clean with thinners. When I am doing covers a different colour I sometimes put a spare set on for painting and paint the covers I will be using separately (Mr.H's covers are Rustoleum Hammered Black).

Looks nice Robert. After reading a few caveats about Duplicolor, listening to my friend Peter's opinions about rattle can paint (Peter is a professional auto restorer) and my friend Bob's opinion (Bob is a regular on this forum-Pony Ruiz) that it doesn't hold up to gasoline, I've decided to go 2-part urethane for the engine. Same stuff I'll be using on the rest of the bike. Peter will be doing the painting. I'm doing the prep work. Peter told me he's used this stuff on lots of water-cooled engines and he's never had a failure. The process is prep, epoxy sealer, 2-part urethane paint. Not cheap but should be a one-time event. I have to go to Wesco to pick a color. It'll be something akin to Duplicolor cast iron.
Should I ever actually complete this project, I'll post some pics.

That's a good way to go if you can. The single advantage of spray can paint is that it is easier to do touch ups if/when needed because there is virtually no set up.

FWIW, I have had no problems with Duplicolor Engine Enamel and any fluids on my bikes, or with Plastikote Engine Enamel either, which I have used on gas tanks a few times.
Duplicolor touch up paint, on the other hand.... A buddy once painted his bike with that. When he filled up at a self serve a few days later his glove jammed the trigger and the paint washed right off.
