Re: ***** Need some help/info Please! *****

For effective sand mark removal you need a rotary buffer with either wool or foam cutting pad and M105/M95 compound. You can get some rotary machines below $100 at Amazon. I saw Black & Decker one for around $80 with speed 1000-3000 rpm. Better buffers like Makita 9227 and Dewalt 849 cost closer to $200. As speed setting you need between 1200-1500 rpm for compound sand mark removal. Foam cutting pad creates a lot of heat so check it out frequently. Follow with M205/M80 Polish.
Sometimes you can remove 2000 grit sand marks with DA polisher but it's not guaranteed.

And that's a real good way for him to destroy his new paint job since he doesn't have experience using a rotary.

A DA can and will remove 2000 grit sanding marks using M105.

Wool pads cut faster but create more swirls. Foam cutting pads overheat easily after intense work so you may burn your paint. Both should be fine in your case. I like W4000 but it's not suitable for tight areas because of its 8" diameter.
Better rotary buffers guarantee smooth work and steady speeds. Many people like Makita 9227 because the speed range starts at 600 rpm which is great for slow polishing or waxing. If you want a light rotary buffer Flex has some really good models however German technology costs more.

thankyou, great info, I am very new to this, is there a big difference between buffers? or would pad selection be a bigger concern as long as you have the right speed? Also would you think i could get away wtih a foam cutting pad if i wet sanded with a 2500, or would you just use a wool pad after the 2000?

any suggestions on a setup less than 100$??

are the buffing compounds I have going to work with the right setup? or should i take them back and get something else?

You will most likely not be able to do much as far as removing the sanding marks with your cheap 10" orbital. You would be much better served using at least a Dual Action polisher and appropriate buffing pads, but even then it will take some work to remove the marks.

okay, I just finished painting an entire truck with base/clear, and I wet sanded through 2000 grit. i have the following products:

- medium cut cleaner
- fine cut cleaner
- swirl remover 2.0
- machine glaze
- cleaner wax

which of these products do i want to use? and in what order?
I am using a cheap 10" da buffer I got from o'reilly, and 3 different covers/pads..
