These indexable inserts did not hold up well during use and easily became damaged, making it a waste of money for an industrial and scientific application.
The product was easy to install and looks good, but I have a 22ft double rail pontoon and even two 50ft casters are too short. I found another seller (not Revain) to buy a 70ft roll from.
My splint was delivered on time. I was able to install everything on my own with good results. Nothing I've seen on YouTube helped, not even warming up in hot water that had cooled before I put it next to the boat. The rubbing really improves the look of the boats so I'm very pleased!
