I have a ton of this stuff laying around and I just took the muffler off the bike and removed all of the rust with my wire wheel. I bought some high temp rustoleum, but I figured I'd hit it with POR15 first to be sure. BUT, POR15 is only good for 600 degrees F. I don't want to redo this. I have no pyrometer to measure the surface temp. Anyone try this? | ||

Somebody posted in one of the Uly threads that they'd wiped their muffler down with cheap cooking oil (canola IIRC) to prevent rusting. He said the oil never smokes even when the muffler's at its hottest, which means the temp must be less than 450 degrees F. If that's true, it sounds like you'd be fine with the POR15. | ||

Having used POR15 on engine frames and especially on parts that attach to hot things like turbocharger downpipes which can get well over 1000 degrees... I would say POR 15 would be kind to you. It is a great product. Lets us know how it turns out and take some pictures. | ||

por 15 is shiney, glassy looking..i dunno for a muffler. | ||

The muffler won't likely be getting hotter than 600 degrees F. | ||

I didn't think it would get over 600 degrees, especially the entire thing. Just wasn't sure about the area near the collector. Just wanted to make sure. POR15 is glossy, but since it is UV-sensitive, I'll be using a high temp matte top coat. | ||

As a rough rule, look at your headers. Where they are blue indicates that the temperature reached about 600°F. Further from the exhaust, the pipe will be a yellow straw colour which indicates about 400°F. I'd figure you were safe to use that on the muffler. | ||

About calling the manufacturer, most of the times they are able to give a more accurate answer since they have done product research and know what can and can not be use for. | ||

POR's Chassis Coat Black is a little flatter than the standard product. Not flat, more of a semi flat kind of color. I think it's much closer to the stock can look than the gloss would be. They don't give a temp rating on it, but they say it can go over the standard rust preventative paint. I've used it on car frame's before and just like all POR products, it's awesome! -Hemicbx | ||

+1 Hemi I coated the majority of the frame on my Grand National with it and I LOVE the way it seeps into the metal and sets. Great product. | ||

I used the original gloss as a base and top coated with some high temp matte black grille paint. Looks more gloss than matte, but good nonetheless. |
