So I tried this Vivid stuff and I think I like it

Saw this on a you tube cruisers channel and decided why not... Did all my overhead windows in half a day. Very impressed with the results lets just see how long it lasts. It is built for outdoor use so i am hoping I can get a year out of it for $50 in materials well worth it.

On a flat surface it's not bad. On a compound curve surface it's a PITA to deal with.

Expect a year or so and you'll see edges coming up.

like any window film it's not a bad idea to go around the edge with some clear coat.
