I didn't use any primer or anything else, just cleaned painted/lacquered surfaces with break cleaner and plastics with xylene.
Without primer or edge sealer it's easy to take the film off just by warming it.
On tight bendings it might be good to use primer on plastic surfaces but NOT on painted.
Time will show how the film will stick and how it will react to heat exchange.
On my bike's tank there is different kind of wrap film (wrapped 2 years ago), it was something Italian Easy Wrap.
I think it's better on hard rubbing surfaces, the 3M 1080 may not be good in that kind of use.
On the contrary 3M 1080 is better on tuning and does stretch easier and stick better on bendings.
Compare different wrap films before buying, on flat surfaces the film can be thicker.
