I had mine fitted here ...
Boat repair, boat repairs, fibreglass boat repair, fibreglass boat repair, gelcoat repair, yacht painting, yacht restoration, yacht refit - Pedros Yacht Refinishing in Devon
Very expensive at about £160 per metre. They usually only do the bow section or the first third of the keel.
The stuff they used on mine is fitted using a 2 pack adhesive and I understand that its not exactly an easy job.
Its been on there 2 years now and I launch and recover solo from a concrete slip about 60 times a year, also I very often run up on the river beach to buy live sandeel before I head out to sea.......... this stuff is magic and tough as old boots. Once washed it just has a few tiny scratches and no wear at all.
I will be buying a new Zodiac 550 next year and it will go to Pedro's for the keel protection to be fitted before I even think about launching it !
