Need advice on this "sunburn"?

[TMT]

Hello All,
I have started the daunting task of polishing Amelia, my '66 Overlander. She has lived in the Florida sun for years!
In addition, the last PO taped a for sale sign on her that has left a really ugly mark. I can't feel any tape left, just see it.
And there is an awful spot that may be sunburn, or it could be where the sign sat for months. I'm including pictures.
She shines up beautifully around the blemish, but I can't seem to polish that away.
I started with Nuvite F9, went to F7. This is what's left.
I'd love to hear from others and how you would tackle this "sunburn".
Thanks in advance.

you may have to go with wet and dry sandpaper to get down to "clean metal".

You MIGHT have to sand it, but do a couple of test spots with whatever you're using to polish. It might just take an extra pass or two. Good luck looks nasty though.

It might be baked-on residual adhesive from the tape used from the sign. Try a strong solvent, like MEK, to see if it can be dissolved--it may be slow to work, but avoids sanding.

Of course, all safety precautions for gloves, ventilation, etc. should be followed carefully.

Thanks to all for the advice. I have hit it a couple of times with F9, and once with F7.
As you can see in the 3rd photo, the metal around the blob shines up great! You can see the iPhone reflection. I may resort to the sanding. Maybe try the MEK on the tape. I'll post pictures after my trials...
Thanks again!

or try a little aircraft stripper to see if it will lift the residue (or any strong stripper). Actually looks like clear coat from the picture.....

Funny I thought it looked like clear coat too.... If Mek or the like doesn't take it off I'd try the rubber eraser wheels they make to take off decals. 3M makes a Good one.

Like these Amazon.com: decal remover wheel

Comparing the first and third picture - after you'd tried polishing an adjacent section of the segment - it looks like you got some removal of clearcoat or whatever right along the edge of the burn mark. Go with the remover or MEK, then try again. It looks like you've got some kind of crap that will come off and let you get a uniform polish.

Okay I have older eyes but looks like bondo to me and if you scuff it a couple to times with 250 light touch please and see what happens.

Again, Thanks to all. Looks like it may be the end of the week before I tackle this again. Rain expected every day until Friday. And right now it's sitting uncovered in the driveway. I'll let you know.

Have you tried paint remover? The klean kutter gel works well.
