I'm in the middle of backdating my exhaust system and just stripped and cleaned up all the tubes that connect to the heat exchangers (stripped, removed rust etc) and now need to know what to paint them with so that they don't rust again. I was just thinking of POR15'ing them, but not sure if the stuff will hold up to the heat. I'd also like to coat the insides of the tubes with something too to keep them rusting out from the inside, although with all of that heat it's probably unlikely.
I am assuming any kind of spray paint and maybe Por15 won't be able to hold up to the heat. Would the stuff that peope use to repaint their mufflers work? I can't afford to powder coating route and am just looking for a cheap way to ensure they don't start rusting. Any advice would be much appreciated. Thanks! |

QUOTE I painted my 911 heat exchangers with hi-temp paint, but the sheet metal surround never got hot enough to properly cure the paint. I would use enamel on the heat shrouds, and hi-temp on the exhaust pipes themselves. Not worried about the exchangers themselves as they are stainless steel. I'm only worried about the bits that connect the exhangers to the rest of the heating system. QUOTE High-temp ceramic coat. Brando, something like this? http://productsearch.machinedesign.com/Fea...fromSpotlight=1 |

Brando, something like this? http://productsearch.machinedesign.com/Fea...fromSpotlight=1 Over 30 years ago, I had mine blasted with walnut shells, prep'd & primed them immediately & rattle-canned them with Rustoleum satin black high temp. They look the same today (very nice), but then, my 914 doesn't see the elements. Still, worked for me! Pat |
