How to remove the dark opaque liner glued on window glass?
I have an old car in which the previous owner glued some dark opaque liner on the interior side of window glass to reduce sun heat. However, some of that liner has been peeled off. Now I want to remove it completely but it seems hard. Is there any substance or way to remove it?
Also, what's the best way to remove the clear coat without causing much damage to the actual base paint coat?
Thanks a lot.
