Powder coat Engine parts

(1/4) > >>

ogri211:
I have My engine stripped down and I am wondering what to do with the crank cases, I am going to polish the outer casings, I know that's not the way they were done originally they were painted, but I like shiny things. My question is has anyone ever powder coated their crank cases, I have a guy who has done all of my powder coating for years and he is very good. I am wary about getting the crankcases done and also I would need to match the colour when I was painting the top end of the engine, I would be grateful for some input.

Sounds risky to me, my experience with powder coting is it's not good on areas which get warm, let alone hot.

ogri211:
I spoke to my powder coater and he seems quite happy to do it he has done lots of parts for me and is very good with the masking and knowing where to leave uncoated  I have not decided yet I may just do it with VHT and bake them in the oven when the Missus is out, I have that paint from DS has anyone used it and is it any good?

Powder coated crankcases and whole top end on a race engine years back. No issues.

I had the generator and sprocket covers powder coated and the finish is fine.
Some minor blemish showed on one where the alloy had minute pinhole corrosion? but other than that they look good and shiny.
Plenty of choice in silver to choose these days too.
Not fully petrol resistant but better than the spray stuff which I used for the rest !
Others also have the crankcase and rocker covers done with no issues in service.
Honda didn't paint the lower crankcase, due to cost or heat dispersion?
