LS Folk. . .Exhaust Paint Test

[Mumford]

Thanks in part to some tips found here, I managed to get my exhaust off cleanly and intact, painted, and remounted without anything being destroyed. While by no means in good shape, there was enough metal remaining to sand down, and get a few coats of paint on. . .To return the favor of those who kept me from cutting my headers apart, I'll keep you all posted on how the paint stands up. . .
Headers:
Prep: Sanded to bare metal with 60grit.
Paint: Rust-Oleum High-Temp Flat Black (spray), no primer as recommended on can. Rated for 1200 degrees F.
Initial Finish: Very flat, almost looks more like a coating than a paint (If that makes any sense)
Mufflers:
Prep: Sanded with 80grit, loose coating and surface pitting removed.
Paint: Dupli-Color Black Semi-Gloss Engine Enamel (spray), over Dupli-Color Engine Primer (spray). Rated 500 degrees F.
Initial Finish: Very shiny for a 'semi-gloss', and looks damned good overall.
First ride summary:
About 50 degrees out, total of about 20 miles, mixed highway and city driving. Not exciting, but I had to work that day. The Rust-Oleum smoked for about 5 minutes (as warned on can). After ride impressions:
The Headers look good, no apparent change except maybe a little bit flatter. The finish on the mufflers is dulled for 3-4 inches behind the junctions, but not bubbled or peeling.
Let me know if this helps anyone, and if i should keep updating once it gets warm enough to be riding again (down in the 20s again in NJ, dammit)

Yes, please keep up with the updates.  This may just inspire me to try something like this with my chrome pipes and mufflers.  I wonder if the original chrome would make a difference?  I would say a good 75% of the chrome on the headers is shot, as it it.  It is especially nasty down by the oil filter cover.  I aways warm up my engine before draining the oil for a change, so when I remove the filter some always gets on the header.  That probably accounts for it.
