take a look at the BMW 650 I did here:
BMW 650 Convertible detail and paint restoration

Deep scratches on the trunk and deep swirl marks throughout the entire body. Everything came out looking absolutely perfect with a high gloss shine even when using a medium cutting pad and no finishing pad. No holograms or light swirls left on the paint, just a perfectly smooth finish.

Plus if you wanted to you could switch from a heavy pad to a light pad mid process and not worry about mixing compounds.

It's totally worth the price and could save you hours working on the car.

This stuff is AWESOME. Put one coat on after your polish/detail. Wait overnight and put another coat on the next morning (or about 12 hours after first coat). It goes on like a wet wax, but you have to remove it before it dries.

One coat works great but after 2 coats of this your friend won't have to worry about someone pouring anything else on his car. Any liquid beads up and runs off like magic.

I started using this 2 weeks ago. Last weekend my car was in the rain for most of the day, then driven in the rain at night. The next day the car looked 90% clean. Instead of dirt being along the entire bottom half as usually happens after rain driving (even after a fresh wax), the water had washed right off and most of the dirt went with it. All that was required was a quick light water rinse and the car looked 100% again.

Best of luck bringing that paint back from the dead and glad to hear it's been going well so far.
