Report and pics showng how much clearcoat is removed during machine polishing

I'd also agree with this. The idea of a heavier compound is to do it faster.
Which, of course, makes them more "dangerous".

Now, if someone could make a polish that corrected like a compound, but didn't remove as much material, they'd really have something going! Hmm.... sounds like a glaze, or a polish with filling abilities...

This whole study is making me revisit the merits of glazes/filling in general, and the actual value of going for 100% correction.
 
If I'm even remotely concerned that correcting something might take off "too much" clear (whatever that means depends on the situation) then I'll often quit the aggressive step(s) just a *little* shy of complete correction. If the Finishing Polish takes it the rest of the way, fine; if there's still some residual flaw when I'm done, well that's fine too. Of course I'm not doing cars for customers who might expect perfection, and I suspect that I have a much more long-term perspective than most people. But not achieving 100% perfection every time I correct some marring just seems like common sense *for my situation* and I bet that factors in when I reach for something potent instead of incrementally working up from "mildest first" (plus, I'm quite familiar with the paints I work on).

I can appreciate a good glaze. I plan to use it on the side panels of my Jeep Cherokee, as it will be used mainly for off road fun. It WILL get scratched, dinged, etc., so no need (or desire) to correct it to Autopian standards. But I do want it to look *decent* in my eyes.

Cool thread.This one, along with another one I was reading yesterday about PTGs or something, got me thinking. I already have some pics I took some time back.

Basically, I can do a "clear coat vs no clear coat" difference. I'm in a position where I can do this, as there is clear coat failure on my daily driver (STOP! This was before I found out about detailing! Don't bash me!)

I'll work on a thread for that, hopefully sooner rather than later. But to give you some idea...




 
Very interesting read. I'm just a hobbyist with four daily drivers in the family. I'm now thinking I will spend more time using paint cleaning all-in-one-type products than compounding or heavier cutting / polishing. You guys are frightening me.

Amigo -

It is way safer to find a Proven compound that comes in many levels of correction, and start with the least aggressive for correction, get the right pad on it (which may take some experimentation), get your technique correct (which comes from hours on the machine), and go with that...

It used to be there were only 3 Major compounds out there - Meguiars, 3M, and Menzerna around these Forums, remember way back then ???
They all actually make several versions from heavy cut to finishing, to even almost nothing for that last bit of clarity if you wanted it...

I have tried all of them for years and have found that Menzerna has the best selection of product, and yeah, they have been making compounds for many of the German automakers for longer than all of us have been alive... (1888) :)

Then, there are a lot of new/newer/newest correction products coming out almost every year that make all kinds of claims, and if you have the time to try them all out, then go for it...

Or, you can go for what has been around longest, has the most hours spent on research by probably some pretty smart people, and is still working every day somewhere, making all vehicles turn out at whatever level of gloss and clarity you want...

I think the best thing that ever happened to those that want to correct the paint once or so, and then Protect the paint for X nbr of years, is the Coatings...

Again, there are well, I only know of 1 that has been around almost what - 10 years and it still works great, and then a lot of others - almost 1 new one a year now to choose from..

You will be fine, just keep reading, writing, asking, and putting in some time in the garage out there... :)

I don't mind scaring you about taking off too much clear ;) At least, not if you plan to keep your vehicles for a long time. The *biggest* thing IMO is to just not mar them up in the first place.

But sure, you simply have to be reasonable- Accumulatorette's A8 ('00 with ~150K) gets used *hard* and yeah..it's gonna get some marring (kids, pets, the infirm elderly...it's just gonna happen) but even with that sort of (ab)use, just avoiding what *is* avoidable makes *such* a difference. I.e., don't mar 'em up when washing and try your best to keep anybody from touching the paint (without being the unpleasant car nut who "cares more about the car's paint than..." if you get my drift).
