paint protection film, any good?

Hi

Because I'm dope I've had a few panels replace on my bug. The bottom of my rear Aeros really cop a beating because they sit so low, I thought I might apply some of this stuff while its all still fresh

Don't know about that brand but I have seen a 4wd with 3m clear protection and it seemed to work really well (the guy that owned it worked for 3m)
Cheers
