A mustang that has probably never been waxed or polished before...

I've got a 95 stang, new to me, but it was a south Flordia car. The body is in great shape, but the paint, not so much.

It looks as though its got a lot of oxidization build-up on the paint. There is a lot of grime too that won't come off with a regular washing.

I tried the claybar method and it works really well at cleaning the body, but doesn't get rid of the oxidization. I also tried a small spot with a rubbing compound and then the polishing compound after. It worked well at restoring the shine but not necessarily all the grime.

I think it may need a bit more work but what is the correct/best process? Would it be best to claybar then use the rubbing compound? Should I just use the rubbing and polishing compounds?

Also, I found the rubbing compound left some scratches in the coating, I assume this is normal. How do I eliminate them?

Thanks everyone....

That's always a possibility. The sun down there is harsh. When I use the compound it shines good. The claybar makes it very smooth.

How do I tell if the clear coat is gone?
