What to use to remove this??????

ya...
WD40 to soften things up. Let it soak for a few mins. Then gently scrape with a single edge razor blade.. I have a scraped with a 4" blade on a 12" handle that would pull that off in 2 seconds.

Then maybe some rapid remover for any residual adhesive.

Finish with a wipe down of denatured alcohol.

Plastic razorblades and Max Professional Citrus remover.
This stuff is great for removing glue left from old vinyl.
Won't harm anything. Paint, Plexiglass, good stuff.
Better than Rapid Remover.
