Soap and water is always first! But with a scuff paste (i use SEM) the added abrasives do help.
The cleaning and degreasing isn’t very important; kinda of a bad thing to be scuffing a dirty panel. 🙂Comet also works well: http://www.howtocustompaint.com/surface-prep-auto-art.htm
[quote]What is the reason that you buff at a low rpm like you do? Have you found it to help with swirls? Do you use more pressure or move slower with lower rpm’s?[/quote]
I mainly wanted to see just how low i can go. And at those rpm’s, i’m moving at a snails pace.
No pressure on the first pass; sometimes pressure isn’t needed at all. Sometimes, only one
good pass will remove 2000 (that tells me it’s way soft). I might add a bit more pressure
and crank it up (or down) on the second pass. It all varies day to day. Could be 1200+rpms…This clear, in particular, sands, compounds and polishes well. It’s on the “soft” side.
Actually, the MS does everything well. Being able to quickly nib with 2000 grit
and polish out is a big time saver.The Meguiars M105, isn’t like the other diminishing abrasives. It doesn’t break down and works
best at lower rpm’s. Not just my findings either. And it feels kinda painful to move so slowly
when for years i’ve been compounding at 2000+ rpm. BUT, the cut is fast and it finishes
down nicely for the following steps. Another advantage, with the slow speed, is being able
to concentrate in tight areas/edges without much fear burning through (big plus for newbies).The manufacturer recommendations are just that. Not very different spray guns…

Many detailers contributed to this list (on going). 3M, aside from the Ultrafina, isn’t very popular
with these guys. And i’ve been moving away from 3M myself…[quote]Seems its always the same story with these people, “I’m not in any hurry, do it whenever you get some free time, work on someone else stuff first if you need to”, yet they check on your progress a minimum of 7 times a week? [/quote]
My buddy was just here today asking about his bug! Basically the same line there. He calls, or comes in
once or several times a week.- AuthorPosts
