Hey guys i just got 1984 Z28 and the rear hatch has some really old window tint thats bubbly qnd gross i tried to scrape it off where the defroster grid isnt but i need to get it off, any ideas how to effectively remove it?

 

iv heard of some putting an amounia solution on( dont quote me on that as idk what it is) and putting a trashbag ontop of that thats covering the tint then close the car up( windows up, hatch closed, t tops on ect) and letting it sit in the sun for a few hours to the bag can grab the tint then just pull the trashbag off and walla!

 

You can spray some Windex(with ammonia) on it and cover it with Saran Wrap.
The ammonia will soften the adhesive and you can use a soft scrub brush.
It's gonna take some time and patience.

 

It seems kinda messy, how about a heat gun

 

heat guns work but its alot longer and you risk damaging the defroster grid in process. the bag trick, or the wrap trick works the best and the fastest

 

i ve had good luck using windex and plastic razor blades on side windows-the saran wrap trick works,i watched a guy do it at the dealership many times

 

I took my whole hatch off and turned it upside down on the ground. I scraped off the loose stuff, sprayed it with windex, then put black plastic over it to heat it up.

After I got all of the film off, the sticky adhesive was still there, so I used some Goof-Off and paper towels for that.

 

I would take it to a tint shop. They charge about $5-$10 bucks to remove it and it takes about 5 minutes. Looks perfectly clean like if it was a new window.
