I have a plastic windshield that I want to tint, but have run into some problems. I tried getting a tint shop to place a film over it, but the surface was too curved. Is there another method that I can try? Is there any kind of spray or dye? Also, I would like mirror tint. Is that possible? The plastic can flex a little, so it has to be able to withstand that.I don't have to worry about whether or not the tint complies with the law. So, there are no restrictions.
If it's plastic, you can spray tinted clearcoat over it. Some films should work. It's what people do when tinting tail lights.
I just would check with a different tint shop. I ran into that issue with my rear window on my car. A few different shops said they couldn't do it because of the size and how curved it was. Bottomline they just didn't want to go through the hassle. I found a shop that was willing and it turned out great. As for the spray tint VHT does make a product called night shades. I've seen it used with mixed results. On something small like taillights it good. But for a a large window you might have issues with consistent coverage. The tint might look blotchy when your done. Once again I would just look at finding a different place to do the tinting for you.
