Have any of you tried POR 20 on exhaust? I am thinking of cleaning my pipes and painting with POR 20 before reinstalling on the car. The website says heat resistant to 1400 degrees. Anybody out there tried this?

 

I used the POR15 factory manifold gray, it's rated to 1400. I think it came out good.

I also used the PRO 15 on my exhaust manifolds and it looks great and has been holding up well.

 

I used a POR 15 product to paint my engine. It is an excellent paint. It resists heat, can be applied with a brush and remains glossy despite engine heat. Make sure the parts are SUPER CLEAN before painting.

 

X2 Make sure you get the complete system. If you dont treat the are as per the directions the paint wont stick well. I will actually peel off in sheets.
