Recommend a hi-temp paint brand for exhaust?

[myap]

Anybody have any luck with rattlecan brands fr. Kragen (and the like)?

I've rust and faded paint on the Kerker of my 750 that I'd like to sand down--what grit sandpaper should I be looking to use?

TIA!

150->300->600
BBQ black, high temp black, etc.

just sand it really good with 220 :emory cloth works killer, use a strip like you were shining shoes, holding each end, and working it back and forth around the pipe.

the ceramic base dupli-color stuff works ok, just remember with exhaust paint LESS IS MORE,...keep it as thin as possible, and it'll last the longest.

VHT probably makes the best rettlecan high temp exhaust paint around, I see it at road rider, and others

if ya have trouble, gimme a PM and I'll help ya out

VHT baby, that's what it's made for. I've used the duplicolor high temps a lot at work, and can tell you they don't work like advertised. They do spray really well though, and finish with a nice gloss, but tend to discolor or cook through with exhaust temps.

Awesome, thanks guys. Will 220 emory and VHT here I come.

VHT all the way. good prep work is essential, and follow the directions on the can.

You really should sandblast the part before painting. Depending on how deep the rust is there will probably still be some remaining in the pits that will require repainting in the future. Besides, it will give you adhesion that sanding cannot compare to.

Highest temp paint you can find (ACE carries 1200, IIRC). Good prep work, essential. Final and true secret is baking the paint properly (to drive out volatiles). Instructions say one hour at 600 degrees or two hours at 300 degrees. What my son and I did when restoring the exhaust on his GS500 was progressive warmup. No way could we fit the exhaust into our oven

So after reinstalling, we started the engine and let run just until the header at the exhaust outlet was too hot to touch, shut down and let cool. Did this about 8 times over the course of an afternoon, until the whole exhaust was getting hot.

That paintjob has held up for > 2 years.

I sanded down my R1 cans, primered and thinly spray painted flat black. So far (did it about 2 months ago), the look hasn't changed too much. I think it was Dupont possibly I got it at Home Depot for like $5. I'll double check the brand tonight and take a couple pics for you and post them tomorrow.

Smart! Thanks for that tip.

Here are the pics I said I would post. Sorry they aren't the greatest quality, I was in a little bit of a hurry I guess I should have cleaned them too - they have a bit of grime on them but you get the idea.. and it wasn't DuPont after all, it was Rustoleum primer and flat black.
