I had the same "issue" when I got the RF tag for the express lanes in my state. I bought some clear cling vinyl and stuck the tag to the vinyl, cut it out, and then stuck that to the window. This is what I used: https://www.amazon.com/gp/product/B002J6CO9I/ref=ppx_yo_dt_b_asin_title_o01_s01?ie=UTF8&psc=1 .
I just know that if I did the windshield I would forget about it and not say anything until the guy at the gas station is actively scraping it off along with the old sticker. Either that or get deployed and have to rely on my wife to get it inspected while I’m gone.
Virginia just needs to do away with those state inspection stickers. My new Tahoe is black with black leather interior and I definitely burned the back of my legs when I got into it while wearing shorts yesterday. I’m trying to get this tint ASAP.
