I have a header that had a crack by the collector. The crack was welded up and ground smooth. The area around the weld and the weld itself no longer has the protective coating on it. Should I just paint the area with hi-temp paint or is there a better solution? It was ceramic coated, or appears to be. Thanks.

Any suggestions?

 

cermic coating inside and out try out these guys

If the whole header was previously coated, I'd just use paint. I wouldn't expect more than 600* at that point. If nothing else, look into the tech line DIY coatings: http://www.caswellplating.com/aids/techline/

For just a smaller spot, it should be perfect. There's a few guys here that use that stuff, and it works great.

I'm going to have to suggest that you stay as far away from HPC as possible.
I have a Full-Race header that was treated at HPC and in less then 200 miles the coating started to fail. Instead of honoring their warranty, they made a general disclaimer that their warranty doesn't apply to Full-Race products. $300 wasted

As for your problem, I would also suggest just some high-temp paint. To get the entire header re-coated it would have to be completly cleaned and then coated. Probably an extra expense and a basic coating runs around 300$ anyway.

 

High temp VHT will work wonders. If you're looking for a thermal insulation, this is what you're after. Spray it on lightly - too much and it will flake off. Be sure to get the high 2000*? VHT.

Yeah if your going to coat anything use Swain Tech coating. the best coating by far. Alll the others are just high temp paint

 

I went to a place that sells wood stoves. They have a lot of different colors of paint in spray cans. I painted my downpipe and turbo 2 years ago and it is still holding up. It hasen't even changed color. GREAT stuff.
