VHT engine enamel for body parts
Thought I would make a contribution to the knowledge base after coming up empty handed when I searched.
I was looking for a really rugged paint finish for frame, fenders, tank and other tin on a Honda CB77 restoration project I am doing. Powder coat, 2K urethane and so on are good approaches that I have taken before. I started reading about the durability of ceramic finishes being used on guns and spent some time looking for ideas. Cerakote and the like are a little spendy and most are to be applied by pros. Being a DIYer I wanted to try my own version.
Turns out VHT high temp engine enamel is somewhat similar to the pro coatings - a urethane finish with ceramic filler. I had used it on engine covers with excellent results, and upon finding that it comes in gloss black (the CB77's original color) I decided to give it a try on the CB77, starting with the forks. After a careful soda blast, fill, prime, sand regimen I shot two light coats and one medium coat all within about 30 minutes. That needs to dry overnight then has to be baked at 200 degrees for 20 minutes to cure properly. After baking the finish seems very tough. Though it's quite shiny, it doesn't really level out that well and I had some blushing on a couple of pieces. And that is the issue that I couldn't find info about - would the orangepeel finish polish up OK?
Turns out it does polish up nicely. Here is a shot of the painted and baked fork tubes. The tube on the left is unpolished. The tube on the right got a wet sanding with 1500 grit and was polished with No.7 white polish.
Of course I can't can't speak to long term durability, but so far I am very pleased with the results.

Looks good... I did the VHT high heat on some exhaust guards with good results.
Several coats per the label, then, into a 200°f bbq for 30 min, 400° bbq for 30 min, and as close to 600° bbq as I could get (~550°f) for 30.
This finish is still going strong after two years with no sign of change.
I've used their chrome paint too on a gas cap. Kind of like what you did, still holding up fine.
I've been pleased with their products and customer service.

I only sprayed this stuff on a few months and the passenger pegs are already worn >: (
Probably because I used the on-bike cure method.

That much prep, expecting long term durability? Why stray from powder coat or 2K? For a quick scuff and shoot I could see using a rattle can, but when you want it to last? Hopefully it will exceed your expectations.

Looks very nice. VHT has always made products that impress me. Keep us posted on the durability and progress on the bike.

But my main intention was simply to share whether the paint would polish out.
