Anyone Tried 3M PI-III Extra Cut (05936)?

[Accumulator]

Before I banish this product, I want to know if I'm just using it incorrectly. I've tried it by hand, Cyclo, and rotary (slow, medium, fast speeds) with different pads.



It seems to be liquid sandpaper, *lots* of marring (not micro, either); it seems like it goes from very aggressive to flashed without breaking down much, no matter how I use it. So it leaves nasty marring that's almost as hard to get out as the scratches I was using it on!



It seems to work a lot better on ss than on b/c (as do many aggressive products), but since it's a PI-III product, I would think that it has some b/c application. I keep thinking that I'm just not using it correctly, but I've tried everything I can think of....any ideas?

Sounds close to Super Duty RC and I cringe everytime I open it. I reserve it for my mid exhaust pipe now.

I used this with great success with a pc and wool pad to remove 1500 grit wetsanding marks on my black ss paint. I followed it up with 3M Finesse-It II Machine Polish 39003 with a yellow cutting pad and the paint was super smooth.

Accumulator,



Have you figured this out yet?

stiege - Thanks. I used it with decent results on SS, but it still left more (not-so-micro) marring than I would've liked. Like you, I was removing serious scratches on SS and then following up with a more reasonable product. But on b/c, forget it. It just scours the finish way too much for me. Maybe the wool pad makes all the difference; I was only using foam and some products do work a lot better with wool.



stevet- nah...things are happening regarding the Volvo, so I'm not experimenting on it any more- now I'm trying to get it presentable/back on the road ASAP. None of my other vehicles need anything like this stuff so I'll probably make like Bill D for now and use it as a metal polish.
