Anyone had any experience of this stuff? POR 15 Rust Preventative paint
http://www.frost.co....ainting_v35.pdfFound it mentioned on classic car website whilst hunting for exhaust paint options past Sperex and PJ1 etc, and it was rated.
Have a Laser pipe to fit and I want to coat the downpipe to silencers connector before fitting, and was thinking of doing downpipes before the winter weather commuting starts as they are going a bit. Was going to redo the starship Enterprise once it off too.
Looked at Ceramic coating as previous thread mentioned this lot

I've yet to find an exhaust paint that will withstand the effects of winter salt etc.
The best compromise I found for the 2-strokes was Exhaust paint on the first 10" or so then black hammerite. The hammerite won't take the temp any closer to the engine.
As 4-Strokes run hotter I used exhaust (PJ1) on the whole thing, you just have to keep on top on the rust problem.
Tried PJ1, Sperex, & Hammerite Bar-B-Q paint.
I did hear of a process that sprayed aluminum onto steel and then you just paint over the top and never goes rusty. It was in PB many years ago on a readers special. Never tried it.
You just can't beat stainless steel for exhausts
