any thoughts on this product?

Looks like a good idea. I wonder what happens if you left it on for longer than one should for whatever reason, would it be hard to peel off?

 

Sounds similar to the product made by 3M. I'd try it on an expendable vehicle first, especially with one product review.

 

I used something similar (on a Jeep) for a cross-country trip.
1/ seemed to be doing a great job for two days
2/ driving through rain on third day washed most of it off
3/ what was left after the rain and two more days of driving (five days total) was extremely hard to remove
