The cover for the cockpit of my boat is in great condition, but it's not waterproof. The material is a soft synthetic knit fabric. Neither side seems to be coated. Any ideas on how to make it waterproof (again)?

i think i saw something in a west marine catalog. i need to re waterproof my canvas. should come in gallon jugs.

I use "Starbright Waterproffing and Fabric Treatment", can get it a West Marine. Spray it on to thoroughly wet the canvas. Works well and lasts about a season before needing a new treatment.

"Aquatite", it is a silicone base material, works great.

I use this stuff, I think it's called "Igloo". Comes in a white bottle with purple writing. My wife got it at a fabric store. Anyway you put your cockpit cover in the washing machine with a full water level. Pour this stuff in, let it agitate, then let it sit for 10 minutes, then let it finish the cycle. Mine still beads water after 14 months.

Thanks - I'll give one of them a try.
