$199.00? I’ve only found it for $299.00
I used to work on cars, RVs, etc. for a living and I’ve seen plenty of bra type front end protectors. They all damaged the finish, no matter how well they were secured.
After looking at the website pictures of this thing, I don’t see any way it would not do the same (especially only being secured on 4 corners).
My suggestion is save your money, use wax or 303 regularly and wash as needed.
The Star Brite PTFE stuff in another post looks interesting (and much cheaper). May give it a shot.
