So I had a boat last week. A Crownline 18SS. We took it all apart to get a good clean install since the boat was in really good shape and it had never been apart. We tinted the side triangles with no issues since they were flat and the pass through as it was the same. The two curved windows are were the problem came in. We got the passenger side done with just a minor issue which we solved pretty quick but the drivers side window has been completely different. The film won't stick to the glass. I know this sounds crazy but here's what we've tried. It's been hot and humid so we've had a lot of slip in our solutions lately but we tried with a little less, no change. We tried with no slip and it still wouldn't stick. I even tried a alcohol water solution and that didn't even make the film stick. I even went as far as just straight up film with no slip to the glass and it still wouldn't stick. I was so bad that I put a piece on there, let it sit for over 20 minutes till the customer showed up and showed him that it could be moved and taken off with no residue. We use Global QDP on everything and I've never had this happen.
I've never seen this before, ever!
So I'm asking my fellow tinters. What's your thoughts on this?
I did clean the glass with straight alcohol, heated it from both sides, steel wooled it and tried a torch to see if there was something on the glass. Nothing worked. It's safety glass for those that wanted to know and I'm able to shrink the film to fit. It's the only window that isn't done on the boat as the other curved window did not have this issue.
Let me know your thoughts, comments, solutions etc.

Thanks!
