I had a can of Rust Oleum Flat Black on the shelf. Thinking it's a good color to cover the original muffler, I Painted. Looks good. About midnight it hit''s me...High Temp??? (IMG:style_emoticons/default/huh.gif)

The can label shows it ok up to 200degrees. So...how hot does the muffler get?
If it's not going to work, can I paint a high temp paint on top, or do I need to strip this off? (IMG:style_emoticons/default/chair.gif)

It will be gone the first run. Even the high temp stuff comes off after a while usually. You need to get all that off before you put high temp on it, otherwise it will burn the paint under it and just start flaking off.

(IMG:style_emoticons/default/agree.gif) .... but you'll probably see a mess of smoke as it burns off, esp. with Rustoleum's additives! (IMG:style_emoticons/default/barf.gif)

Get all the Rustoleum & now crappy original paint off, then get some VHT or similar high temp paint - IIRC you need 1400 degee stuff on them - both primer & paint. As with headers/HE's etc. good prep & good priming is as important as proper hi-temp paint.

BTW - stock color was a flat or satin grey, although many prefer black.

VHT is available at most FLAPS, but here's a link for their colors & primers:

Here's the 356 resto supplier with the same Porsche exhaust system grey which those guys & many of the CW's here use:
