Looking for advice what to use to help seal/water proof my boat cover it is made of the heavier denier Sunbrella Fabric.
I have had it 9-10 years and have never sealed it,the boat has only sat outside 2.5 years since I have owned it,Previous owner stored inside,due to needing some garage space this year for a project it will be sitting out in the elements so I thought I would seal it.
Any thoughts on the 303 Products Aerospace Protectant Sunbrella recommends it.
Appreciate any other suggestions !
