Let me start by saying these door panel covers are a game-changer for window tinting. I've used them on over a dozen cars now, and when they fit, they're absolutely brilliant.

The waterproof PET material is durable as heck - I've reused the same set multiple times without any tears. The 43.3cm width works perfectly for most standard car doors, and doubling them up gives you solid coverage.

Where these really shine is keeping door panels dry during tint application. No more worrying about water damage to sensitive electronics - just slide these bad boys in and spray away. The protection is top-notch.

Now for the downside: that black insertion lip is THICK. About 30% of the cars I've worked on had weather stripping too tight for these to fit properly. When they don't fit, they're basically useless.

Storage is super convenient though - just roll them up when done. Much better than dealing with flimsy plastic sheets that tear after one use.

Final verdict? If you tint professionally, these are worth having in your toolkit. Just don't expect them to work on every single vehicle - keep some traditional methods as backup.
