Other What type paint will work on your engine?

[227]

Just exactly how hot does our engines run? Do we need the 500 degree rated engine paint or can we just use regular paint for an engine? The reason I'm asking is because I bought some Dark gray 500 degree engine paint and after it dried it came out a different shade, kinda gold looking. I then bought silver and that dried with a bluish tint. Is the color variations because its high temp paint?

I used normal temp paint on my cylinder\cases and they held up fine. Though Im not sure how it would hold up on hotter things like the head\exhaust manifold, because I used high temp on those

I've used various colors of high temp paint and don't recall any of them changing tints. They may have gotten a little lighter or darker but that's normal in almost every paint.

did you shake the cans sufficiently?

I used a primer and PJ1 engine and case paint on my - it's held up fine.

the engines in our skis dont really get that hot. normal paint will work, but its just not as durable when it comes to gas and oil ect.
just what ive found anyways....the dupli color engine paint is what i use now. ive rebuilt hundreds of engines (not ski engines) and painted them with that. and it holds up quite well. im just not a big fan of the clear coat...turns yellowish and hazy somtimes.

I rattle can everthing, clear temp paint on exhaust manifold after polish, it lasts about a year then you have to do it again, chamber lasts a long time.

Sand blast the cases/cylinder on my SJ I jeweled the blasted parts then painted candy right over the blasted/jeweled parts. on my 927 i used an etch primer then base coat and 2 coats of clear
check out the link for pics of my SJ.

I disagree that our engines don't get hot enough to justify high temp paint. It may be fine up north but down in the south where the water can get over 90°, it won't hold up. I tried using regular paint in the past and after one ride in the middle of the summer, the paint was toast. The cylinder may stay cool enough but even with dual redundant cooling, the head, head pipe, and chamber get too hot. Even my aluminum waterbox is borderline too hot for normal paint but it has mostly held up.

well yah,
those parts get real hot depending on your setup.
but those parts you mentioned are not motor parts.
they are exhaust parts and those need to be powder coated or ceramic coated or just raw. here in OR you could probably get away with a good automotive paint but your right if h2o temp is 90deg then yah that will make a big differance.
