Ok, Rahul. That's it. I guess we just gotta spell it out. LOL.. How
to polish depends on what is being polished - that's part of why
there's not "hard" answers out there. It is basically a three step
process, though: sanding, polishing and buffing. Each of those could
actually be broken down, too, but I'm trying to keep it simple. The
piece is sanded first, either with sandpaper or "rubber wheels" -
Cratex, Shofu, whatever works. Then you polish it. A basic setup that
almost everybody uses is a 6" muslin buff and some bristle brushes
for the tight spots (wooden hubs, black bristles - sizes are up to
you). Those are charged with either tripoli or white diamond, which a
refined tripoli, basically. It makes no difference which - it's
whichever you prefer. Greystar is much more aggresive, and you can
use it, but it's usually used on a splitlap. Then you clean your work,
and use a sewn cotton buff of 6", and bristle brushes again if
necessary. Those are charged with rouge - red, green, white, black.
Or some other things - Zam is great on silver. Personally, I live on
white rouge, and we have some "apricot" colored platinum rouge that's
great. That's all there is to it. Work on the lower half of the
wheel, never catch the top edge of the work - you'll find that out
soon enough, and watch hair, shirtsleeves, etc. There are hundreds of
devices, compounds, etc., but you don't need those until you think
you do. If you do as I say, above- a muslin buff - they are yellow or
the new blue ones work good. A sewn cotton buff, which will be white.
White diamond, some red rouge, white rouge cuts faster, maybe some
Zam, and you'll be in business. The polish step (tripoli) is simple -
just about everybody uses some form of tripoli. The buffing is
different, and if you find that your compound isn't doing it for you,
by all means try another one. The rest of it is skill, and practice.
One tip about that - each step must be complete. You're not going to
remove sanding scratches with red rouge. Just be thorough, basic
polishing isn't that difficult.
