I have tinted windows but not used this product. Frankly I would not even attempt to tint the back window of an 82 corvette.
Two reasons only:
1. any dust, lint or dirt will show up as a bubble 10 times the size of the dirt, lint or dust that caused it.
The only way I know to get a window really clean is with a razor blade.
2. I'm to old to be laying on my back under the window with my arms in the air and liquid stuff (sop, water and whatever) dripping in my face.
That said I say a real nice tint job done on an 82CE. It was done professionally.
Now for something you did not ask. Tint is ok in the daytime. But at dusk, any low light or at night you need to understand that you cannot see anything that is behind you that does not have lights on it.
I would put up a curtain behind my seat and drive around for a while to see if I liked it.
I know this is not what you asked but I have had cars with tint on them and would never do it again. Almost backed into things some of them living.
