I attempted "screwed up" putting window tint on the rear window, Does anybody still make the spray on tint, can`t find any at the parts stores

 

The spray stuff (if you can find it) is not worth the effort. Shop around for prices from tint shops you'll be better off in the long run.

 

Yep, I guess your right, If I was smart I`d find a rear slider with tinted glass, but that`s "if"

 

Tint isn't that hard to put on, give it another shot!
Just make sure the glass is CLEAN!! And use a water bottle with a few drops of Ivory dish soap to squeege the film. Cut the film a few inches big and trim at the very end. On the other hand, if its just the rear window, a tint shop shouldn't charge more than $20-30. Good luck!

 

Maybe try removing the window and tinting it that way? I've done it on two trucks now, it isn't that hard. That includes all the windows; door, wing, quarter (supercab) and rear. Took about a day to do them all. Making sure the winows are absolutely clean and using a lot of water (with a little soap added) will produce great results.
