White dot on roof of car in plan car view

How long is the G1 meant to last, say on the roof and rear screen?

I'm thinking of their G5 as it can be used on perspex too so can do the B pillar cameras which I think are perspex. But doesn't look like it will last as long as the G1.

It mentions around 20k miles or around a year on the front screen (i did 3 coats on front screen, 1 coat on rear as instructions mention)

The bottles are tiny (10ish mils), so does not go far enough to cover all windows

Have had it on for around 2 weeks now and still working (you still have to use wipers and clean/wash the screen but you do use the wipers less and the wipers instantly clear the screen)
