Cut and buff edges?

[dhutton01]

Sorry guys, but I have 2 more questions.
What buffer speed for compound using a dewalt 7" rotary with 3D wool pad and 3D 500. I've read slow, up to 3000 rpm. I used 1000-1200 so far and it looks great but not getting any heat which I thought I wanted. so maybe I can get more shine out of it.
The section with the concave body line I did mostly by hand and after cutting I can still see sand scratches. If I go back and sand it, Do I start with 1500? I use 1000 1500 2000 2500 and 3000 before the wool pad.

No heat for a novice is a good thing imho… . Just so long as you get it looking the way you want.

The answer on which grit depends on the grit of the scratches. 1500 should be ok but using that many grits removes considerable material. It’s really hard to answer without being there. Use your best judgement….

Thanks for the honest answers Don. I think I'll put it on the back burner for now and deal with it in the fall when the weather is to cold to paint... Who knows, maybe outside it won't look that bad.
At least I know what to look for moving forward.

With that white using a little black dry guide coat will really show you where the scratches are.

i always run wool around 2000-2200 and foam around 1300-1400 but don is right. for a novice, just go slower until you really get the whole process down. better slow and take longer than burn the paint and ruin something

Thanks Jim and Don, Ya both called me a novice so I guess it means I'm moving up in the paint world....LOL
All kidding aside I like knowing what the pros do, it helps set limits and understand how it's really done. For me starting at 1000 was scary enough, but I did eventually bump it up to about 1400 for a bit....Thanks again.

How prone are the edges to damage once you have gotten to foam and at that lower speed? Thinking not so much door edges but moving over radiused surfaces, or reveals.

In my Michigan redneck opinion, you should be really careful on anything that has any kind of an edge. Think back to when you're sanding down the car, those are always the areas you'll get to bare metal first, the same applies to buffing as well.

So make sure your buffing pad is well lubricated, that you're buffing off the edge (and your buffer is held at an angle so the pad is NOT rotating back onto the edge), go at a low speed and don't dwell.
