using a PC around lips

Anthony A said:
One of the biggest mis informations in detailing IMO is that a PC can't damage paint. Besides being wrong it is total BS. How do you correct paint defects? You level the paint. How does paint get leveled? It gets abraded away down to the level of the defect and the defect is now gone. Pretty simple concept. So you are removing paint/clear coat when you do this. There is only so much clear coat to work with. How much depends on the car and area you are working on. PC's remove paint that is how they correct defects. Remove too much and you are SOL. Don't think this can happen? Get a cutting pad and a compound like SSR 3, 3M Perfect IT II or III Rubbing Compound, or something similar. Apply multiple applications on speed 6 with some pressure and see how many times it takes to hit base coat. I have seen it done several times. In fact I have seen it done by hand as well. Clear Coat is not in never ending supply. You can't act as if it is.

Very true; although my understanding was/is that the PC is incapable of removing enough paint *at a time* to do that much damage unless the paint has been polished MANY times. So if you're starting with a new, or new-er vehicle, and not using too many extremely abrasive polishes, it will take hundreds of polishing hours to compromise the clearcoat.

What if you have no clear coat?

Then you remove base coat. Remove too much and you hit primer.

I thought he was asking if you approach a single stage (urethane enamel, enamal, acrylic, etc.) the same way as a base clear system. I could be wrong, but I'd like to hear an answer if I am right.

In my experience, a "burn" on b/c systems softens, wrinkles, goes dull, etc. In single stage, the same thing can happen--top coat comes off and what is underneath either smooshes together with it or is revealed. But I found in working in different shops that single stage "burns" more in the actual sense of burning, as in grabbing and going to metal.
Now that is based mostly on acrylic and acrylic enamel. I've never seen a urethane enamel paint burned.

They are single stage paints, no clear coat. Really doesn't make a difference in how you polish. Weather it's base coat clear coat or single stage. You level the paint with an abrasive until the defect is gone. If you remove to much you are in trouble.
