Ferd/289 Posted February 17, 2008 Share Posted February 17, 2008 I was in a paint shop today and noticed 3M 'finishing discs' that are used on orbital sanders with hook and eye attachment. They felt like a smooth plastic on the surface and I was wondering how they are used. Ferd Quote Link to comment Share on other sites More sharing options...
280zjoel Posted February 17, 2008 Share Posted February 17, 2008 They could be 3000grit sandpaper for the orital sander, i use em alot when wet sanding for buffing, and man do they work great. Quote Link to comment Share on other sites More sharing options...
spork Posted February 17, 2008 Share Posted February 17, 2008 If It's a 3000 grit disc like mentioned above, then heres how you use it. If you have a hood that needs polished, you can hit it first with 1500 dry on a DA Sander with an interface pad (its a foam pad that will make it easier not to dig into the nice flat surface you just painted.) Then after you get the orange peel or dirt out of the finish, you'll go back with this 3000 grit disc and use just a little bit of water and run this over your hood. This 3000 grit disc will take out the 1500 frit scratches and actually start to bring some gloss back to the panel. Then you hit it with a buffer and you're done. It'll cut down buffing time and woks pretty good. They're kind of expensive for the do it at home guy though. Quote Link to comment Share on other sites More sharing options...
Ferd/289 Posted February 17, 2008 Author Share Posted February 17, 2008 I figured that they cost a lot. Where is a place to get less costly 1500 and 3000 wet and dry sp? Local paint supply shop? Ferd Quote Link to comment Share on other sites More sharing options...
Globerunner513 Posted February 17, 2008 Share Posted February 17, 2008 I just used 2000 after the 1500. Maybe 3000 would be a good step above. Quote Link to comment Share on other sites More sharing options...
OlderThanMe Posted February 17, 2008 Share Posted February 17, 2008 I can get up to 2000 grit at the local autozone. NAPA has even higher grit papers... Quote Link to comment Share on other sites More sharing options...
