noticing my muffler is starting to rust, thinking about coating it in POR15 to stop it rusting, i live in pa so salt eats everything

wanted to kno if anyone used this stuff on a heated surface, the regular POR15 is good to 450F, high heat is good to 1200F,

how hot does a muffler get, prolly close to 450F?? which one to use, any other suggestions?

finally got around to coating my catback, used the original por15 gloss black,sanded all the rust and grime off first, used the starter kit with degreaser, metal prep, 4 oz black, put 3 coats on and still have half a can left, hung it from a bunjee on a basement rafter, stuff goes forever. drove on a long ride two hours long, didn't seem to burn off at all still looks nice a gleaming, checked how hot right after I stopped and was only hot at very end of muffler not near enough to burn though

also wet sanded the tips to a polish, can see yourself in them
