Can you over polish with a PC?

I know that the best way to tell the paint thickness is to use a gauge. But is there really a way that you can tell when you have done it enough on a car. This may kind of like a stupid noobish question, but I am starting to wonder if I am potentially thinning the finish on my car too much. My car is a 7 year old car, driven every day, sits outside, red, and has the typical GM hard finish. I have polished the horizontal surfaces 4 times since I have owned it. All times using 6.5" LC CCS orange and white pads using Danase Swirl Abolisher II and I, except last time I used 5.5" LC CCS oranges on my 7424. I usually work the SA II at 4 or so passes on speed 6 on the orange whenever I have polished. I don't think that these polishes are that agressive when compared to others out there, but I am no expert on this and know that pads can change the agressiveness too.



What is your take on this, is this really considered agressive polishing or a strong enough combination that could really be sheeding a lot off the finish? Just wanted to get some opinions
 
I've asked this question a few times and I've never been fully convinced by the answer.



Since I work with a DA, I've always been told that I am likely removing SO LITTLE of the clear, if I am only polishing once or twice a year, it is unlikely it will ever result in enough removing of the clear to cause problems.



Of course, in a perfect world I'd have a paint thickness gauge, but since I'm only a weekend hack, I can't justify the expense.
 
RedlineIRL- Sure you can overthin clear with the PC, or even cut all the way through. But it takes a lot of doing.



UNLESS your car was subjected to some aggressive polishing that you don't know about, I wouldn't worry in your case. What you've described doing doesn't sound even remotely aggressive to me, and I'm a bit more conservative about such stuff than many (most?) people here.
 
"Username:" please remove the Michelle Bachmann pic from your post; makin' me nauseous. I'm from MN and I can tell you, she is dumb as a post.



Thanks,

Unfortunately, NO!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! X 1,000,000. Being from MN, we have had to put up with her antics, misstatements, outright lies, and stilted logic (or total lack, thereof) for too long. Believe me, she is really, really DUMB, and it is only a matter of time before she shoots herself in the foot and takes herself out of the running for Pres. She makes Palin look like a Rhodes Scholar.



So...sexy? As they say, I wouldn't @#%& her with your !$%*.

I am going to try using some Meguiars Ultimate Compound with some LC orange pads, and if that doesn't work a couple passes of M105. If that doesn't work I'm calling in an expert I guess. I know that these are faily agressive, but on harder GM fnishes am I going to sacrifice much to worry about?

I suspect it's most likely that you'll quit before you completely resolve the problem. And I'd consider living with what's left rather than paying somebody to take off more clear.



When you say "a couple passes" I hope you're not being literal, as two passes with M105 isn't much IMO. Four or six oughta give you a good start.
 
I'm new to this so would like to clarify what 4-6 passes means. Do you mean doing a 2' x 2' area and then going back and forth horizontally then vertically over the entire area 2-3 times each way (making 4-6 total passes) moving at about 1-2"/second or do you mean redoing the same 2' x 2' section 4-6 times cleaning and reloading the buffing pad each time. I just did my car and I did the former (only loading the pad 1x for each section and going horizontal then vertical 2-3x each).

Yeah..."passes" gets used in different ways and it can be confusing.



In *this* context, I interpreted it as meaning "redoing the same area a few times", your second definition.



Most of the time, compounding away clearcoat to remove significant marring takes more doing than most people expect, even with todays pads/products/polishers. That's just IMO though, and I might be mistaken :nixweiss I also don't want people to go nuts with this stuff; at the first Autopia G-T-G in St. Louis, a pal of mine damaged clearcoat using just my old (original model) PC with a big ol' 6" Meguiar's 7006 pad!



Oh, and Welcome to Autopia!
 
I always figured a "pass" meant a complete application of compound or polish on an area of a vehicle until the product breaks down.

Two passes would mean doing an area twice.

I am kinda a stickler for using word in the english lanquage how they should be used and not making up our own definition. I would suggest that the term pass should be used as the definition of the word in the dictionary states. Pass : to go by. This means that if you make one pass you would go by the same point once. Hence you pass a car on the highway, you go by it once...
