Mine is three years old. I would say it is far more durable than I imagined. Gentle washing is all it needs.
I''ve had a few dock scrapes with it and was sure I had laid a long scratch in it. A gentle wash and it was gone.
A friend has a 48 ft Krogan. It has about an acre of
Awlgrip. You have to go deeper than the finish to damage it.
It costs a lot. It also needs a skilled hand to do it like it was meant to be done.
The only bad thing is it''s onlty the hull on my boat done with it. The cabin and decks are much more worse for wear.
