Detailing help

Image Unavailable, Please Login Image Unavailable, Please Login Sorry not a Ferrari, it's a Porsche. It's an outside car as my garage is full with my Alfa project(stalled) and boxes of stuff from my son moving back home(don't ask!). However, it is under a cover the majority of the time, not much sun exposure. I've been pretty good with wash/wax occasional polish/clay etc., could do better, though.

See the pictures, I will try to get better pics once I can pull out of the garage. Note the cloudy spots in the 2 areas in the rear. There were others which I was able to make disappear with hand polishing but not these. I will try my porter oscillating polisher when I can get to it, maybe that'll do it. Do you all think this is oxidation or possibly from the cover rubbing? I kind of think it's the latter because oxidation is not fixable with polishing, and it did get better with polishing. The rear of the car is the only place I see this, nothing on doors or front of car.

The other picture is my Boxster S script, it was broken in a couple spots so I removed it. Worked on it for awhile with Goof Off but really didn't do much given all the foam on there. Techniques/products to help with quicker removal?

Lastly car covers. After some pretty expensive covers with soft insides failing way too early I went with a quality waterproof cover that is unlined. Good fit but is definitely causing small scratches on the rounded edges of the car and possibly the hazing. I like this top but wonder if there's something I can put under it across the hood and the rear to protect those areas from future scratching. Maybe a couple pieces of felt or other materials?

 

Better pics, finally able to get to my porter reciprocal polisher and worked on, slightly better than hand but only slightly. Not evidence on hood or anywhere else of this. Do I take fine grit wet sandpaper to this or is the paint toast from oxidation?

this is after some ash from a nearby fire, so doesn’t look great in other areas

New pics. Also got the script off and glue removed but still see the script after polishing. Guess I’ll have to install a new script as sanding would be needed. Sorry no additional pic of it at this point. I was able to improve the cloudy spots with medium cut but not much. Maybe sanding or something more abrasive, prefer to stick with doing by hand with something more abrasive.
