Buffing 101

I had a little to much orange peel for my taste and decided to buff. I started with 1000 and moved to 1500 on a DA. Im using 3m perfect it compound then 3m swirl remover with 3m foam waffle pads, white with compound and black with swirl, does the wool burn I mean cut faster?.I always seem to have scratches that are only visible with your nose touching the panel but I would still like them gone. I am aware of a more abrasive compuond, is that recomended? If for example someone were to sand with lets say 800 on clear( why they would do that I dont know), And keeped bufing it over and over with compound would those scratches still be visible? Does the compound act as a liquid sand paper? And Im wondering if its not scratches underneath that Im seeing. All I know is that I hate scratches. Im good at buffing but want to be great at it. Any advise would be great. Thanks

Don't use a DA for color sanding, it's to easy to scratch it.
Use a block by hand it's the safest, some use wet, some dry.
Most sand to 2000 grit before buffing.I like using lots of water.

Buffing compound does remove scratches, the larger they are, the longer
it takes. Some big ones take forever to buff out and is to easy to burn
the finish trying. Always sand to a finer grit first. It's faster in the long run
and will give you a flatter finish.

I have always had a problem with wool pads leaving a few pigtail scratches,
I have gone to foam pads exclusively and eliminated the problem.
The foam is slower and less abarsive so....
I now sand to 2000 grit and then go back over that with a
"Abralon" pad (by Mirka) that's 4000 grit. on a palm sander (and lots of water)
It gets rid of all the scratches and leaves a semi-gloss finish that buffs
out super fast, even with a foam pad.
Most times I can skip the rubbing compound altogether with this system
and buff it out with a polishing compound, a milder abrasive.
I don't get any scratches this way and it's about as fast as using
the wool pad.

Always treat wed sanding(or dry sanding) like block sanding.You could make a perfectly straight body very wayy if you use a DA.
