how often can a polish be used, without any problems ?

Given OEM clears are thin, 1.05-2.0 mils ? How safe is a *swirl remover* polish like PI III MG from 3M if used twice a year ? I mean, although polish are soft OEM clears are very thin. 1.5-2.0 mils in my eyes is ever so thin, albeit heard, at least the first .5 mil. I like to keep my cars a long time, thus I prefer to use polish msot of the time instead of fine cut compounds. However I may overestimate the cutting power of a polish here. I'm not a professional but an enthusiast detailer who cares for his cars.



I'd like to hear from your profesionals on the above issue.



Best regards

Marc,



I think you're safe. I'd be cautious about fragile single stage paint on vintage cars or something like the lacquer finish Accumulator has on his old Jag. As for modern clears and the Autopian practices owners go through for them, I'd feel confident :up
 
Humm ok, well I asked this because using 3M's polishing pad as well as their PI III MG which I love, I went quite a few times over the whole car, as some sort of practice....hope I haven't cut too much into the clear :eek: :scared
 
Yeah Marc, I'm kinda stumped by that, All I could say is maybe you just need to follow with a PC
 
the pc works fine and the good news is I'Ve been able to remove 98% of the holograms with the rotary alone...but I'll finish with the PC for sure.



It took time but I'm pride of the results :D



I gues it should be ok for the PI III MG to be run many times on thw whole car given it'S very soft and designed to remove swirl marks..let's hope so.:D
 
Bill,



have you noticed that pads whose fibers/pores are stretched may create marring/swirls ? I've noticed that recently. I was trying to remove holograms and my major mistake was the pad being too old, and it's pattern was not tight enough.....I'Ve always thought the tigher the pores/pattern the less swirling it will leave behind.



Later





P.S. Sorry to be such an extremist lol I can't help it ;)
 
He he, not extreme to another extremist at all! :xyxthumbs



Nope I haven't seen that, but it sure does make sense. I just had bits of foam shed off a black pad after lots of application with Klasse AIO over a period of over a year, to be expected. So, I just use that pad and one or two "disgraced" pads for a bonnet to be placed over them.



In fact on the PC , on a seting of 1 or 2 I'm finally going to try to find use of my cotton bonnets and go over my seats with it once I've Lexoled them. I bet it will work faster than buffing with a towel by hand.
 
I wouldn't use a rotary all that often on a "keeper", even with the 05937. Maybe with something milder like 1Z WPS, but if I were marring the paint enough to need all that rotary work I'd work on my wash/dry technique. And if the paint is *very* soft, I'd really watch it (I've thinned the Jag's soft paint way too much using a PC/Cyclo just because we're talking 19 years of polishing).



And yeah, pads are one of those "renewable/expendable resources". Use 'em up and toss 'em. Using a worn out pad defeats the purpose. But with a PC/cyclo they can last a long time. Especially the griot's ones, they just never wear out.
 
Paint Thickness:

German and Japanese cars: 4-5 Mils (1 Mil=1000th of an inch)

With the exception of:

Lexus-White and Tan: 5-7 Mils, Lexus- Black and Silver: 4.5-6 Mils

BMW: Silver: 6-7 Mils

FORD: Approx. 5.5-7 Mils

GM Cars and Trucks: Approx. 4.5-6.0 Mils, Jimmy’s and Blazers: approx 7 Mils

Chrysler: Approx. 5.5-7 Mils (Note Sebring hoods are fibreglass)

Dodge Cars: Similar to Chrysler

Dodge Trucks and newer Ram Pick-ups: Cab approx. Mils and the boxes approx 9 Mils

Jaguar: approx. 6-7.5 Mils (but they tend to vary)

Jeep Grand Cherokee: These read approx. 6-8 Mils, Wranglers: approx. 4.5-5.5 Mils

[Don’t remember the info source]



This may give you an idea of what thickness (should be thinness) you started with, if you take a measurement with a gauge you can check what’s left and then progressively track what you are removing.



Not very scientific but a SWAG is better than flying blind…



~Hope this helps~
