Bimini Water proffing

[Pontoon Don]

What is a good product for spraying bimini top to repel water ?

303 Fabric Guard is a very good water repellent.
I get it online because it’s rarely in auto parts stores.

303 Protectant (for vinyl) can be found in auto parts stores and is far superior to Armour All. It’s non-greasy, great UV protection, and goes on very easily. Can do all the couches on a pontoon boat in just minutes. Can be used on plastics, like consoles, also.
