Step 5:
Cleaned exhaust tips w/ alcohol & rag. Car had not been driven for over 14 hours or so, so no fire risk! :]
Scuffed up tips with fine Scotch-Brite.
1 more alcohol wipe.
Got a can of Rust-Oleum 241169 High Heat Ultra Enamel Spray, Black, 12 oz:

Masking tape tight around the exhaust tips. Then more tape to hold lots of newspaper around the bumper areas to catch overspray.
Then, also used a handheld cardboard sheet for extra blockage when spraying.
Sprayed down about 5 coats on the tips, including some down the the pipes themselves. Waited a few minutes between coats.
Pulled off masking quickly thereafter so I could run an alcohol-soaked rag around the bumper to catch any overspray that I might have missed, before it dried. My masking was good--I didn't find any paint on the bumper.
Waited several hours before driving. No smell or smoke when driving, a possibility per the spray paint can. I don't think these get too hot--there was actually a paper sticker on the underside of the right tip, apparently from the factory, that was beat up but not singed or burned off.
Looks awesome. Still looks good 3 days later, & easy to touch up in the future if needed.
Whee!
