So, rather than start a new thread (Confessions of a nOOb), here's an update for those who are interested. I did finally end up with the Goit's Garage 6"/LC 6.5" pads (assort yellow to blue)/Meg's UC/M83/M80/M03.
I'd thought I'd learned a bit with the Toyota 4Runner that I was selling. I was wrong. After washing/claying/washing the Passat, I saw what looked to me like minor swirling and a few isolated scratches. After a couple of false starts, I ended up using
Meg's UC/M83/M80/M03 over the whole car. Took quite a while and I didn't get out everything I thought I should have. Used UC/LC Yellow,
M83/LC Orange,
M80/LC Orange & M03/LC Blue.
Looks very nice, but not as nice as I'd have liked.
So, here's what I think I learned:
I got a feel for the DA itself. Using the 6.5" pads seemed to be fine since I couldn't really stall it out. But I've got a 5" backing plate and some 5.5" pads on the way anyhow. I think I might have a little better control with them. I also got a feel for the speed and number of passes as well as product control.
I succeeded in my plan to learn with the older products (M83/M80). The
M83 wasn't aggressive enough for the correction I was trying to perform (more on that in a second). As far as the diminishing product goes, I clearly see now why the non-diminishing products are popular. It seemed that I had little time at all to work the product on the surface before it broke down. I've placed an order for the
M105/M205 combo to use on my Nissan.
For me, the biggest thing that I think I learned was what is meant when the phrases "cutting ability" for pads and "aggressiveness" for products is used. I was more than a little tentative about "jumping in" with
M105. It is listed as 12 on the aggressiveness scale and is non-diminishing which means that it is on the top of the scale as well as works as long as you want it to - I imagined seeing polished sheet metal. Sure, I could probably over work the
M105, but now I realize that using a LC Yellow or Orange pad and making 4 or 5 passes with diminishing pressure will not remove my whole paint structure. Again, for me this is a breakthrough, being new at this, I was worried about ruining the paint.
And lastly, I learned that the M03 did indeed add to the depth of the shine I achieved. That could very well have been a result of filling in some of the marring that I hadn't removed by using
M83 instead of M105, but the difference between the look of the surface after
M80 and after M03 were noticeable.
Thanks for all of your help so far and I appreciate all of the recommendations. I keep coming back to Google with "Site:Autopia.org....." when I think of questions. Knowing now what I know about M83, I see why M105 was recommend. But I'm glad that I learned that M83 wasn't aggressive enough rather than that M105 was way too aggressive for my needs. For a material that seems to scratch so easily, it sure seems to take a lot to get the spider webbing out!
