Yes I just tried it out 2 weeks ago, I used ONR as lube and I mixed 2oz to 32oz to make sure it was very lubricating. And it marred the paint pretty well, I was compounding so it wasn't big deal, I was also disappointed at its ability to get contaminants out of the paint as it seemd like it just didn't pull them, I will stick to clay

I use the Magna Sponges before machine polishing. I dont see marring but I dont apply any pressure.
