Polishing aluminum to chrome finish and
protecting it
++++
I have a 2002 Suzuki GSXR that I would like to polish the
alluminum frame and swing arm. They have a very nice brush finish
with a clear protective coating that is pretty durable. (not sure
what it is) It takes some heavy grit paper to sand it off thus
scratching the surface underneath and causing even more work to
prepare it for buffing.
What will strip the protective coating without damaging the
alluminum, and what should I protect it with after I polish it to a
mirror finish?

Sandpaper is the solution your looking for. You can start with a
220 grit and it will eat right through it, or if your worried about
then having to buff those scratches out then go with a 320 or 400 and
you will be there longer but have a smoother finish when its gone. My
advice would be to use 220 or 320 with a air or electric sander,
works great!

The coating must be some kind of transparent paint, I would
submerge it into some thinner liguid for a nite in order to get rid
of it, then I would use polishing agent(wax) to make it shine,
finally, apply a coating on it and make it last.

I have done a lot of polishing and I have had to deal with the
stuburn clearcoat many times. I found a product called
Aircraft Remover [link is to product info at Amazon] that will
strip off the clear coat quickly. It does come with some careful prep
work though. You must cover up any surface yo u do not want stripped.
Spray it on the area you will be sanding let it sit till the clear
coat is bubbled up(wrinkled and separated from metal). you can wipe
it off with rags or hose it off, but it will wipe right off leaving
naked metal.

Then use 400 grit sand paper and hit entire area
completly. then wet sand with 1500 paper thoroughly. once
you have finished you are ready to buff that to an awsome
shine. Use buffing rouge and a high speed buffing wheel and
it will amaze you. I have done this to several motorcycle
engine cases that were plain aluminum and the results look
better than chrome to me
