My 70 Road Runner was recently painted with b/c (2-3wks ago), using PPG Glamour Clear. From 5ft away the paint is spectacular, however, up close at angles there are abrasions evident in the clearcoat. Difficult to describe the abrasions, so I included a picture. They aren't extensive but enough of them (areas) that I need to deal with it. Pic1: the abrasion is evident just above the reflection of the light, middle area. Pic2: series of lines. I've successfully used 3M Perfect It II to remove paint abrasions on a gelcoat boat hull, with a low speed buffer. Would Perfect It II be OK for this clear coat?

Looks like sanding scratches maybe?

Who painted it?


If it was not you, and they color sanded and polished the car, I would take it back to them and have them correct it.

It appears as though it needs more polishing. Many compounds leave a film that hides the result of their polishing, if you polish a little more it may remove the scratches. This is one of the reasons I stopped using Perfect-It and switched to Sure Finish.

George...taking it back to them is unfortunately not possible.

Len...could you identify the product that would work best for this, what procedure you would use, and how long to wait.

Thx
Rich

It depends on how much needs to be removed to get it smooth but I'd probably sand it with 3000 grit Trizact then polish it with an orange foam pad and Sure Finish.

Thx Len. For the hood its just the area in the first pic. Should I redo the entire hood or can I just treat the area with the blemish?

Is the Trizact applied wet or dry?

Would my Makita 9227C work ok with the sure finish hook/loop system?

Thx again.

I would probably start by sanding and polishing just the problem area then wipe the hood and take a look. If it looks better than the rest of the hood then do the entire panel.

Trizact is used wet. We usually use a pump sprayer bottle to spray a little water on as we sand.

The Makita backing plate is good for wool pads but you need a 6" flat, hook and loop pad for the Sure Finish foam pads.
