I used disc's on my Craftsman and found it to work very well. The scotchbright style also worked by I wore them out in a matter of minutes.

I agree the wire wheels worked best in the small areas but I also picked more wires out of my hands then I care to remember.

 

I agree here. Wire wheels are good for tight spots, I use them as drill attachments rather than on my grinder, but they can be dangerous. I've had them catch on loose clothing like a t-shirt and rip the drill out of my hand. Also had one eat the skin off my finger once, hurt like hell. You have to be very concious of them.

I suggest you get a small wire wheel for a drill, only for the tight spots, and go with the abrasive pads like above. I'm actually running a rubber pad with flat abbrasive pads on top of it. Takes a while but gets the job done. I've done about 1/8 of my car with it and I suggest you start off trying aircraft grade paint remover and the type of abrasive pad the gentlemen I quoted suggested. I got some to test it out, nasty goopy stuff, not what I expected, but it definitely gets the stuff off. Cut right throw paint and primer after a few minutes of sitting and the only pressure being a paper towel pushed across the surface, with some downward pressure.
Also, even with the flat abrasive pads (like I'm using), just like sandblasting, you have to be concious of warping the metal if you leave it spinning too long on one spot. I'll get some pics of my setup and post them in the next few days. 2 or 3 pics would say more than all this crap I just type out... on my smartphone... my thumbs now hurt and my eyes are burning...

 

All that crap I wrote, and I colmpletely forgot to say what grinder I'm using, the whole point of this thread... plus no edit button, time to write another essay on my smartphone...

Anyways, I recently got a new Dewalt drill, its nice, great feel to it, comfortable to use, holding up well. But my old man has a Makita in the barn that's damn near bulletproof. I wouldn't be surprised if its older than me! Its old, dirty, not exactly as comfortable to use, but of course, it was made in the past century, what do you expect?
I would suggest another Makita, but I'm hesitant. The idea of "quantity over quality" has always been evergrowing, so this old Makita grinder might not be the best testament to the build quality of its successor. I could be completely wrong though.

Just give it some thought how much you'll use it. My old man has a habit of overpaying for tools of higher quality, even when they see little use, but that's 10 times better than buying a cheap tool that breaks.

This is relative to your life but I do encourage you to consider paying extra for higher quality tools if it fits your budget. As much as I dislike my old man going on tool shopping sprees, I am thankful for quality tools. And who knows, maybe you might be handing you tools down to a son? Sounds rediculous but my old man has a big, heavy, clanky power drill from my grandad that he still has and still works. Makes a weird/scary noise when spinning up, lol, but its gotta be 40 or so years old...

 

i have been slowly replacing my power tools with the Rigid brand. I have found them to be superior in almost every way including price.

 

Then there's special tools for tight places…
