I need to remove a yellowing clear bra from a bumper that will be repainted. When I heat it with a heat gun and try to scrape it it melts. Any easier way?

 

Use one of those garment steamer.

 

I use a heat gun at low heat and peel. If the bra has "crystalized" plastic razorblade or bondo spreader works best.

 

Thanks guys. I'll give it a try. When I try to peel it it rips and when i heat it it gets gooey.

 

I took mine off after leaving the car outside under the hot mid-day sun of Los Angeles in the summer time. I started with one corner and slowly peeled away. Came off nice and easy with no residue.

Maybe the heat gun is too hot. Maybe if you held a space heater to it...

 

I did the same thing as above. It just peeled off in one piece (the stuff is THICK). I had to use a decent amount of Goo Gone to get the glue off though. I had 3M installed on my car.

 

You are using WAY to much heat. It just takes a little. A hairdryer or steamer will work better for you.
