You can't put the static cling on the inside windshield? only sticks 1 way?its works ok I found installing it on a warm sunny day and make sure all air bubbles are out I didn't and it came off once but I like it cause around here I cant have that much tint on the windshield so it wont pass inspection. so by using the cling tint I can take it off for inspection and put it back on after. the first time I had it on I was able to get 100mph without a problem the 2nd time it was raining bad and the car got splashed at 40mph and it came off this time so far its been up to 75mph and no problems so.
soapy water and a good bit of good ole sun would seem to help in addition to an absolutely clean window. I had to redo some tint, and that SH!7 was straight up hard to peel off!I think it depends on whether the print is a reverse, or normal print. I prefer it on the interior, but like my Bulls decal, cling is on the outside. Just had to clean the window to keep it sticky. Doesn't come off even in the rain and with wipers.
