Maybe the OP doesn't want to make the same mistakes you've been making for years.
:cheers::applause::cheers:
Taken with a grain of salt from that poster, (
reading what he's said in a number of other threads as of late).

For instance... might read what he's posted in the high priced detailer thread.
For many a weekend warrior / Autogeek type... they may get away without a PTG. Maybe even if they do a few vehicles for friends even. But I can't IMAGINE a world where a full time detailer, especially one that buffs paint on a daily basis wouldn't own a PTG. (
Especially after more than 2 decades.):dunno: Those "mistakes" that were mentioned.... are where even a basic unit would have paid for itself time and time again.
And tape.... lost for words there.
Guess a dedicated wheel bucket, Daytona Brushes, Wheel Woolies, 2 bucket method, upper panel and lower panel wash mitts, (God forbid Merino wool ones), as well as multiple grit guards and such would be fools play huh?
Ah, there's my issue. I was thinking 30-40 micron was just the clear. That's total paint to the metal.
:xyxthumbs:
Unless you've spent thousands on a ultra-sonic film measurement gauge that has the capability to differentiate between various substrates... all you will - EVER - get is total "film" to metal.
That's why you see guys talking about taking measurements of jambs compared to outside panels. The clear in jambs is generally less than outer panels (
sometimes not any at all), which... (
if that factor holds true in your given situation) gives you a better base measurement where you can compare the overall measurements to the jambs and guesstimate the added clear (
over what you're seeing in the jambs).
Of course comparing all the panel measurements (without the jambs) is where you'll pick up aftermarket painting and repairs. The key is overall uniformity more than anything else, which gives you the real picture of what is going on.
And if it were not complex enough already... we're now into having manufacturers spray a primer-base then clear! (Rather than a true primer, THEN a base, then the clear.) There have been many recent threads actually talking about this on all recent Mazdas in fact. It is not uncommon to see film build in the 70 micron range!
That however is just part of the overall picture. It could still measure that thin, but being a primer-base type paint along with clear. Where if you compared that to a primer, base coat, then clear coat with the ultra-sonic gauges you might find that the clear is the same general thickness overall. :dunno:
Hey... buffing paint isn't rocket science. But if you're not approaching the field with some sort of scientific inquisition and wanting to know more, learn more, and be better at it... might as well do a Google search and find a qualified local professional that DOES.
