What to use to waterproof mooring cover?
 

Some people say thompsons waterseal and the others say the stuff from west marine. What are you guys using??

thanks

I've always used the Starbrite product. Wash the cover every spring, let it dry and water proof it. Never had a problem with it leaking even in pouring rain. Cover is about ten years old. I was also wondering about the Thompsons. The Starbrite is over $20.00 a gallon. Is the Thompsons less expensive ?

Sunbrella recommends 303 protectant after a good cleaning with mild soap.

Our shop has always used Thompsons on the soft tops for our cars. ( Benz dealer )

My interior guy told me about the thompsons water seal
I laughed. But I tried it . Goes on milky white.
When it dries you cannot even tell you did it.
It worked awsome! I could not beleave the results.

Do you just spray the thompsons on?

I've heard of using it before, and it sounds promising. Hopefully a bit cheaper and more effective than the stuff at west marine.

You wont beleave the results

I put a gallon of Thompsons in a deck sprayer (the kind you pump up )and let it rip. Works great. I have a canvas cover and the water beads up and runs off like it's covered with a plastic film. I used to buy 5 or 6 spray cans of the silicone spray. Most of that blew off into the wind while I was spraying. Thompsons is the only way to go in my opinion. I tried the brush method, but it seemed to put on a really heavy (wet coat) and took a long long time. Spraying takes about 10 minutes including setup and cleanup. Leaves more time for standing back, admiring your work and having a beer.

I used the Thompson's on a cover back in the late 90's and it worked great at repelling water but after about a year the cover became very stiff and unflexible compared to before using the Thompsons.
