i did install the invisible shield around 2:00 today and got finished around 3:45-4:00.....wow. but im pretty happy with the alignment that i have so thats good. the only thing is i have some pretty persistent bubbles. i wanted to know if i should continue to squeegee them or just let them sit? will i damage the shield if i should continue to squeegee them? thanks. also a little advice for anyone trying to do this: put the back piece on first! i say this because you need the most spray for the back because it is very difficult and you will have to keep wetting it to position it correctly. the front part is not difficult at all i got it to lay perfectly. i did the front piece first and ran out of spray. however i filled the bottle up with water at one point and that worked ok. any help with my question is greatly appreciated.
