I want to sand down my car with a Da sander what type on sand paper should I use and grit. I hear that the 3m hook it system works well. Has anyone use this for thers own projects?

  If your stripping down to steel here is what I learned. Get a coupon for Harbor Freight's 7" variable speed Polisher/Sander (Item 92623) and a bunch of 80 grit disks. Use the slowest speed and you'll see it's much more effective at stripping paint and old body filler. (Thanks Superbirdtom!) I farted around with air and electric DA sanders and they are just too slow.
  Ya gotta get the disks from H.F. as nobody sells the 7" except them but their price and quality are fair anyway. When your done you'll have a rig to buff with also. Stay off the corners and trim with heavy pressure and you'll do fine. I wish I knew this all when I started as I'd have saved a bunch of time and money!  :2thumbs:

My $29 Harbor Freight Polisher lasted about 1 week & Died. As soon as it gets hot it overheats easily & will die until cools down. Then eventually it will just seize up alltogether permanantly. At least mine did. LEON.

I use a 8'' Hog sometimes to strip. Works good for me. Here in this Pic I had to strip a wavy 67 Coronet hood. I started out with 36 grit on 8'' Hog as some call it. This showed up all the low spots that can be seen in photo. LEON.

Being this wavy only way to get straight is to bondo (body filler) end to end top to bottom as can be seemn in this pic.

Store warranty is 90 days, is it as good as others for 100.00 more....no!  :lol:  Mine stripped the entire car and is still going strong though, the trick for sanding was LOWEST speed for me!

My Makita is much better. Even my Dewalt is better. LEON.
