They make a piece that looks like a buffer pad, mounts on a drill. It's a non-scratch material but abrasive. That may work for you.
you can also youse brake fluid on plastic too! i buy 1/2 a$$ built models at garage sales and refinish the plastic bodys on them. its an old modelers trick. you could also youse goo gone? its cheap and it works like a charm.just leave it on over night.
Heavy duty grinder will remove the shadow ,but will also remove the chrome, i'm not really helping am i , sorry bad idea. NMCC
If you can't get it off with Aircraft Remover, it was probably an electroplating and not a sticker. Glob it on there, let it soak. Nothing can survive that.
this is going to sound weird. but try a paper towel soaked in coke. (thats coca cola not cocaine) leave it on for a few hours and use a putty knife to scrape it off. kay p
Call a local sign shop and see if they have a MBX Vinyl Zapper. Looks like this: It removes the sticker without harming the surface. Glen
WD-40 breaks down many adhesives. So does ammonia. I would try the ammonia first. It is the best thing to remove old window film adhesive, probably not too far removed from the sticker adhesive.
3M makes a similar tool that chucks in your drill. the part # is 07498. any GOOD auto parts store will have it. I have use it to remove striping on paint without harming the finish. -Matt
[FONT="]if you are removing a decal from a car that is on a painted area, don’t use a metal razor blade as its easy to scratch the paint. Depending on the size of the job (i.e. small or large) I know of 2 products. There is a video demo at www.decalstickerremover.com. (one does big areas and the other small areas) Hope this helps. P.S if you need a cheap product that is chemical free to remove the goo or adhesive, try eucalyptus oil (its chemical free and available at most supermarkets). [/FONT]
