Well, on the window, at least. I bought new privacy film for my bathroom windows; the old stuff was dusty and peeling at the edges, and had been sloppily installed in the first place, and my pink bathroom wants pretty windows.
The old stuff did not come off easily. Some of it was brittle and broke in small pieces, and the stuff that came off in big pieces left behind old, hardened adhesive. I soaked it with mineral spirits and scraped with a razor. Not fun, but I got it eventually.
The new stuff has a pattern of bubbles, and getting it on straight and not rippled was a little bit challenging. Half-finished.
All done! I like it better than the old diamond-ish pattern, and I definitely like that it’s not yellowed and brittle, and put on with crooked, ragged cut seams right across the middle.
