VHT Flameproof paint

[SoonerRon]

Does anyone have experience using VHT Flameproof paint on their engine? It's advertised to withstand temps up to 2000 deg F. Seems to be intended for exhausts but I don't see why it would not do well head, jugs and case.

I have used it alot on the exhausts of racecars,it holds up well. It HAS to be brought up to temp to cure,though. If you never get it good and hot it will always be chalky/gummy. ALWAYS. I doubt these motors on these bikes get hot enough to cure it. Possibly,I dont know,but I dount it. In my opinion I would avoid it. I hate to burst your bubble,but I would also hate to see you get into a mess.

Do you like the other VHT high temp paint for engines?

Not only chalky, but it doesn't even act like paint if you don't heat-cure it. I had a customer with a harley paint his cylinders with the black. He thought the engine heat would cure it, but VHT says it needs 350 degrees for 20 minutes (at a minimum) to cure properly. His fresh rebuild show bike got a few sprinkles of rain on it, and he had little rust circles where the water droplets were. (well, brown circles, maybe not rust...aren't hog jugs aluminum too?)

So make sure you heat cure this paint!

I have used the other types of VHT paint with great results,EXCEPT on my bike engine I used their high temp clear with ceramic(how does clear have ceramic???)and it yellowed badly! Other than that yes, I like VHT very much.

Yeah, I've heard that from other folks as well. I'm thinkin' I may use the aluminum high temp paint and pass on using clear coat. My original plan was to clearcoat after blasting if the result was shiny enough. However, I've soda blasted the exterior of the engine which, while very clean, resulted in a dull finish.  I guess painting is the next best thing.

Thanks, it does not sound like the flameproof is the way to go. Think I'll try something else!

I repainted my headers with VHT flat black paint.  I'm pretty happy with the results, except that when I put them back on the bike (without pre-curing them) I managed to scratch the paint a little and I'll need to touch it up on the bike (going to do a lot of covering and taping to make sure I don't get overspray).

There alot of paints designed for wheels that made to hold up to fairly high temps. There are alot of aluminum glossy colors to choose from. They are not rated as high as engine paints but most are good for 300+ degrees,which should suffice for these motors.

Neat, good idea for painting the motor a cool colour.
