Hi guys!
There are some reasonably priced DIY kits for ceramic coating around. You'll need a compressor with clean air, a sandblaster using pretty coarse aluminium oxide and a baking oven.
One thing - that stuff does take some serious temperatures, easily!
I saw a guy coating a 2" stainless steel pipe, baking it - and then heating the inside with propane until the metal got glowing red. One would think that the coating would just burn or fall off, but no. Cooled it down again, and it seemed like nothing has ever happened to the part! Amazing!
I have the kit, and working on building the oven for now. I use the heating elements from a regular kitchen oven, installed in the bottom of a custom-built, well insulated "closet".
The coating itself, is horribly expensive. But I'm still going to coat my exhaust for my GT750 P1 - yes, it's a Kawasaki!
Hoping to get it done this summer, maybe also along with the exhausts for my Z1000 ST? I always take photos of everything I do on my bikes. I'll see if I can remember to share some of the process here with You.
