Engine Paint question

Seems to me there was someone on here who had a method of curing VHT engine paint using engine heat, and timed intervals.
Anyone know the thread, or who it is, a search hasn't helped.

Thanks
 
Check the label on the can VHT SP127

I buy my paint in the US as they don't sell the SP127 in Canada.

I run the engine to warm, shut it down, wait 15 mins and then run it again and get it to normal operating temp, then shut it down and the let it cool down fully and it should be done.

VHT SP127 Universal Aluminum High Temp (500 degrees Fahrenheit) Engine Enamel has excellent durability and superior heat and chemical resistance. It is specially formulated to withstand corrosion, rust, salt spray, chemicals and additives of today's gasoline blends and degreasers. VHT's 550 degree engine enamel is a unique blend of urethane and ceramic resins, which produce a long-lasting finish for engines, engine accessories or wherever a tough durable heat and chemical resistant finish is needed. VHT SP127 is part of a multi high performance coating system for the ultimate protection and quality. The coating system consists of surface prep, strip fast, engine primer, engine color, and engine clear. VHT engine enamel dries to the touch in 30 minutes and completely over night. VHT engine enamel only attains its unique qualities after correct curing. Curing occurs with normal engine operating temperatures or parts can be heated to 200 degrees Fahrenheit. Complete application and curing process instructions are also printed on each can.

Thanks, I read the label but no mention of engine heat curing. I also got mine in the USA.
 
I just let my cold engine sit for two weeks. My patience is weak, but I was away on vacation. When I came back, it seemed fine, and still does three years later.

Did I in fact 'cure' my paint?

I just happen to be re-painting my starter cover from the GS750 with VHT engine paint. I say re-painting because I did not bake the paint the first time and gas ruined it! I thought that I would try the 200 degree oven to see if it cures better. My guess is that the starter cover doesn't get hot enough while riding to properly bake the paint as the rest of the engine is fine. Time will tell!

I see you are in the US, so 200 degrees fahrenheit is correct, a few from the other parts of the world (including Canada) that use Celsius, have blistered the paint trying to cure it at 200 C (392 F)
