Polishing stock tips?
Heres a big overview:
1) Sand till smooth.
2) Buff till the desired shine is there.
in a little more detail:
1) Sanding - Start off with a course grit like 60, then work up to less course sand paper, for example 60, 120, 220, 400, 800, 1200. This is where the hardest work is. You can use machines to do it but its not easy to sand tips with a machine unless you spend some big bucks for an expander wheel set up (you can read about that at eastwood.com)
2) Buffing/Polishing - You can use an electric drill with the the buffing wheels and compounds from the $10 set you got at sears. You can also get buffing wheels for bench griders or dremel tools. I think unless you are removing the exhaust completely the drill would be your best/least expensive bet. Start with black emery compound its the harshest. Then when you are confident you have the surface smooth enough, swap to another buffing wheel and use white rouge to bring out the shine. Sometimes the brown tripoli works well in between the black and white if you are doing aluminum, I'm not real sure what the tips are made out of to be honest. But if they are aluminum (and Im sure someone on here knows, but i don't since I have never had that exhaust) use black emery, tripoli, white rouge. You can spring for the blue jeweler's rouge for an ultra high shine after the white as well. Just keep in mind the compounds work best when they only use one per buff wheel.
