Thanks to Socalandy; I have a replacement VIN sticker for the driver side door jamb. The original sticker got mangled and needs to be replaced; it's stuck on the metal pretty good. What's the best way to loosen the adhesive so the sticker can be peeled back and removed ?

Hair dryer or heat gun. Don't get it too hot!

What's too hot ? Warm to the touch ?

When the paint bubbles, that's too hot.

You want it warm but not to hot to touch. A finger nail or plastic scraper will help too.

Use a Popsicle stick or better yet a doctors tongue depressor. . sharpen the end
so it is sharp, like a chisel blade. . use this to ease off the old sticker as it won't hurt the paint. . It's a go slow project, and a hair dryer will give you the right amount of heat without overheating the paint. .

Thanks.

I've found goo be gone to work well in certain applications of the sticky kind...

Don't laugh but they make plastic razer blades. They work well taking off , clear bra's and other stuff on paint with out damging the paint. Use with the heat and
alcohol.

Update: Used the heat gun with a popcycle stick that was filed to look like a chisel. Took all of 5 minutes to remove the sticker. Then I used Terpentine to remove the remaining adhesive. Worked out great

And under the old VIN was the original color of the car......
