I would venture to say that I probably have more sandpaper than anyone that frequents this board, yet, I'm not satisfied that any of the abrasives I have is up to date, current with today's advances in removing paint, crud and rust.

I'm also including wire wheels and brushes. I have a slew of them. Same issue. Is there something better today?

Maybe I'm just getting lazy, but hand rubbing is too time consuming. I used to do most sanding (whether wood or metal) by hand. Now I want to do it faster and better, be more efficient.

3m has abrasives aside from sandpapers that cut through paints to metal pretty quickly.
For example: 3m Roloc bristle discs http://www.3m.com/product/information/Roloc-Bristle-Disc.html

These come in various grits: 50/80/120 as well as diameters: 1", 2" and 3"

Has anyone tried these? Are they any good? Do they last? Are they worth it?

Yes, I've used the green and yellow ones. removes paint and rust quickly. I was suprised how long one lasted. Mabey 15 miniuts of non stop work. Leaves the metal similar to using a wire wheel.

For large arias, the car show guy's have been using a liquid paint striper.

This is somewhat of an old thread which I'm bringing to that top again because it needs updating.

During the months since my original post, my search for a good "sanding" method to remove the old finish from my car was realized. I wound up getting and trying a 4.5" abrasive "resin" disc and a 7" version. Both are hook and loop and attach to a 5/8-11 arbor. The machine I selected to run these abrasive discs is a Dewalt variable speed
polisher/sander #849xp. The abrasive resin discs and attaching pads were purchased through Eastwood.

After using these items on my hood and fender (at this point) both work very well, with the larger 7" disc working the fastest and best over large flat area.

For safety, I've used a 3M brand N95 particulate mask. I also add that wearing nitrile gloves helps keep perspiration off the cleaned metal and "rusty" little finger prints down to a minimum.
