Cuts in paint?!?!

[Farmingdales Finest]

My son asked me today to detail his 2007 Grand Cherokee.

As I was starting to clay the roof I kept hitting these bumps that at first I thought was dried seagull poop. Then after I dried it I saw what looked like 3/4 to 1" long cuts in the paint. There was about 7 of these all within about a 12 inch circle. When I picked at one up came a piece of paint that was all the way to the bare metal with rust.

I am obviously going to have to have it sanded down to the bare metal and repainted but want to make sure this never happens again. Any ideas how this happened? And any tips on what to do for the time being as I really cant afford right now a paint job.

Thanks in advance!

Might need to include a couple pictures so we can get a better idea what it looks like.

Here's a couple pictures. I think someone did this with a knife or another tool because he had someone carve a penis in a window.

Hail damage at any point? perhaps the PDR was done. sometimes on extreme dents, PDR leaves the paint with small cracks in it that moister could have gotten into and then rusted.

Just a wild thought....

No hail at least not in the 3 years we have owned the truck. What's PDR?

It looks like the one has body filler under the paint?

[Farmingdales Finest]

The top? If so that is rusted bare metal.

PDR stands for paintless dent repair
