Heres instrustions from TAP Plastics' site. I used TAPs 5% on my rear and it looks decent. Few small pin bubbles in the corner from DIRT, so be sure to scrape and clean windows as good as possible!! Microfiber towel (12 for $2 @ Walmart) and a can of invisiable glass (about $3?) and your set, also use a razor on the windows w/o defrosters.
