sorry for the noobishness of these questions. i picked up this os looptail pk for a project:

i'm weighing my options between powdercoating and polishing. there's obviously cost involved with powdercoating but i wanted to find out what's involved with a polished finish and if it's possible for someone inexperienced like me to do it. i've seen some great pics of some pk's with the great polished aluminum finish. i was thinking about stripping (question about this down below) the spray paint off then polishing it. is this difficult to do? what's needed? aluminum polish? polishing disc attachment for my power drill or just my hands, some rags and elbow grease? after getting the look i want does it then need to be clear coated? here's what i'd like it to look like:

i've read a few opinions on these 2 paint removers:

seems to be 50/50. i've also read some opinions on aircraft stripper but they didn't seem as favorable.

thanks in advance to any and all replies!

All right, I'll chime in.

Experts please correct me if I go astray...

Your goal frameset looks to be 'polished aluminum' from the start. Whether you want
that or a colored frame is up to you. Either way, you gotta get rid of whats on there.
Take your pick of strippers. It's been my experience that none of them will make ALL
the paint just fall off. You gotta do some scrubbing/light sanding.

I think you'll find a silver alum finish under there. Work that with metal polish, (mother's, met-all, etc) an inch at a time until your elbows bleed. Then do it again. Then again. Two or three more times.

Then I think there are some clearcoats you may be able to use if you want the
polished look. If you want powder, give Chip a call for advice.

Your decision might be made for you once you strip the existing coating because sometimes the condition of the bare metal might remove the possibility of polishing, without a real lot of work and/or money. I have a Floval Flyer which turned out to be a dog once the powdercoat was removed. It's going to be an effort just to prep it to be powdercoated. It's been blasted way too hard and because of the thick powdercoat it wasn't evident at the beginning.

Regardless of the above, polished PKs look very cool and I have one myself.

Or you could just send your PK frame to me. I will polish it for $100 and have it back to you so fast you wont believe it.

this is what i polished out. a new dk octane. the back half is what i polished. i used 0000 steel wool for the welds by hand. on the frame itself, i used auto wet/dry sand paper. started with 600 grit and worked my way up. i sanded all the mill lines out then i used mothers polish to get the bling.

Wow, that DK looks amazing. Well done.

I got a bit lazy doing a similar thing with a PK and only did about half of the seat stays and chainstays on this one.
