I plan on stripping all paint off, down to metal on my front fenders and hood. I have an electric milwaukee 4" grinder. I plan on using a wire wheel to accomplish this. How well do wire wheels work?

Ooooh. I wouldnt. Gonna leave some deep scratches in the metal. Milwaukee sells (or used to) an orbital sanding attachment for the angle grinder. Works great, I used it to remove paint before. Buy a stack of 80 grit 3m paper and go to town. Keep her moving and dont push, let the sander weight and fresh paper do the cutting. JR

I'll look in to that sander attachment. On a side note I killed some time with a wire wheel on an old hood I had. It actually turned out very good. Surface was very smooth, would have to go over with sandpaper to roughen up before primer.

Actually, I stripped an entire truck with wire wheel on a grinder.

Word to the wise: use the 'knotted' wire wheel. They are about twice the cost, but you'll get about three times the run time.

they actually don't leave deep scratches, but I understand why one would think it would. it actually leaves the metal polished. It is probably possible to gouge the steel, but a gentle touch will prevent it. I'm not sure if it is faster than sanding it off with, say, 80 grit, but it will take off bondo too. Again, using a light touch, it doesn't heat the metal badly either.

Never thought wire wheels were good for that? I've read of people going back over the bare metal with a wire wheel to get in pits and such.
I used a orbital sander with 80 grit paper (takes forever) and a stripping disk on an angle grinder (which went much faster, but left deep scratches which i had to run the 80 grit sander back over anyways)... I've also tried aircraft stripper (waist of money, it takes a layer at a time, but its just a nasty product, smells bad and it still ate into my latex gloves).
Just take your time, and make sure you have the patience!!!!!

I also used paint stripper in a spray bottle. I would recommend this technique. Use paint stripper from Lowes. It came with it's own spray bottle and was $20 per gallon. I used two gallons for the entire car. I used a scraper with a razor blade to clean it off. It worked very well. I had several very thick coats of paint and it took it right off with hardly and fumes. I the sanded after to clean up the metal.
