Used Search & read endless threads.....

With all of the variables in this process, one seems to drive the show and that's hardness of the clear coat on the particular vehicle that you're working on. I learned first hand that the VW has some pretty substantial resistance to the cc. And in searching, I've found several references to the fact that the Nissan cc is "soft". Is there a big range in the amount of hardener used by different companies?

And a related question; so there's a range of aggressiveness (1 through 12 now with Meg's). Has anyone ever run across a comparison of the actual measured abrasion (given all other variables unchanged) between them? (i.e 1 being unmeasurable, 3 removing 0.02 microns, 6 removing 0.04 microns, etc.)

I'm planning on trying a section with M205/LC Orange and if that doesn't cut it (pun intended) then going to M105/LC Orange. But there is quite a difference in the level of cut between 205 and 105 (at least by their respective positions on the chart)

EDIT: And then I run across the thread discussing the viability of an abrasion chart on this very site (with a few of the participants listed as Banned....). It seems I've tread into shark infested waters..... lol.... I understand if this portion is left unanswered or commented on......

Yes, hardness can vary DRASTICALLY make to make, and model to model or color to color as well! Example: new Jet Black BMWs... so soft I'd almost not even wanna deal with it - actually, nope, wouldn't deal with it. Lol, wouldn't buy one, rather not work on one. But the same Bimmers in other colors, not as soft.

Because of the differences in paint, as well as user variables like "how long did you work the polish", you really can't put a number measurement on how much CC is removed. Also, as far as the Meguiar's chart, don't put too much stock in it. It somewhat gives you a relationship between different products, but beyond that, it doesn't mean ALL that much in practice.

RE: 205/Orange - yesterday did a FAST polishing job on a girlfriend's Grand Cherokee. 205/Orange knocked out 90% of her marring in a single QUICK pass over the whole car and finished down pretty well (at least as far as can be seen on her silver metallic paint). Until I get more time with the vehicle, that has worked well. When I get it again I'll probably hit it with PO85RD/white or 205/white or 205/white + PO85RD black

Well, I finally got to polish & seal my Altima. As soon as I brought it home, I started searching this site for the best way to keep it shiny and black. Learned a lot from reading, used my Toyota 4Runner as a test, used my wife's DD (Passat) as practice and yesterday I put pad to the Nissan.

Looks great! I thought I could get away with M205/Orange, but ended up using M105/LC Orange with moderate pressure and then a form of KBM with M205/LC Orange. I probably could have hit it with M205/LC White, but I really didn't see a big enough difference between the passes (White vs. Orange) especially since I buffed with very little pressure on the last pass.

I do like the M205! Definitely easy to use, even for a novice. I'd planned on hitting it with M03/LC Grey since it really brought out the paint on the Passat, but I was disappointed in the finish it left on my black paint. Almost seemed like it took the finish back a step... not sure what was going on there.

So now I've got a good coat of OS on it (2 apps about 1/2 hour apart). I plan on putting a couple more apps (1 this am and one more this evening). Even considering using an app of 845 instead of the 3rd app of OS......

Thanks again for all of your help and advice. I'm really happy with the results and look forward to keeping my vehicles looking there best from here on out.....

djs134- Glad you got good results. As you found, what works on one car (M03) won't always work the same way on another. For some reason I find this really applies to the Meguiar's Pure Polishes.

drew.haynes- You might be *shocked* at how the PO85RD improves upon the M205

Looking forward to it!
