Personally I'm not a fan of sticker bombed rear windows
My foglights were a disaster so I got new ones at cost through my mechanic. The haziness on the left isn't dirt, it's the actual lense, I tried polishing them last week but it literally didn't make any difference. Applied Lamin-X to the new ones but I'm keeping them inside until they clear up.
Took the battery out too. It was down to 8V last weekend when I tried to start it. I was starting it every week but I got lazy over the weeks of Christmas and New Years so it died. Going to keep it indoors for a couple days to warm up and then attempt to charge it, I'd really rather not buy a new one since the plan was to get a lighter one and mount it in the trunk in the next couple years, after doing some more important stuff this year.
