So just had all new canvas made including a full enclosure. Love to hear what products people use to keep the sunbrella in top shape.

thanks

I use the 303 family of products for cleaning and waterproofing. Seems to work well but I am sure there are others. Make sure you don't get the waterproofing on the stratoglass. I think Practical Sailor did an article on canvas cleaning and treatments and that was one of their cautions.

The only product approved by Glen Raven Mills (Sunbrella) is 303Fabric guard.

FABRIC GUARD 16 OZ HIGH TECH 303
I wish the previous owner of my boat had used this stuff from the beginning! I have what is the most beautifully executed canvas I have seen on a boat, heavy duty, beautiful details, and very functional, but the sun-exposed surfaces are unrecognizable in color from the rest. It looks like two different colors.

I assume it will all have to be done over. With my new budget constrictions II think I may be doing it myself! I have a walking foot Alpha-sew machine (same as non zig-zag Sailrite) that someone gave to me, and a big roll of "toast" Sunbrella. Oh, well, maybe I'm kidding myself. I'll start by just trying to make some winch covers and teak handrail covers.

I have used the 303 Marine Aerospace Protectant on my AB CSM RIB since new, and it looks great after 6 years, except I still have those pesky dirt spots in the texture of the fabric. I used bleach and a brush on my old RIB to address that, but I think it may have done more damage than it was worth.

So, sorry for the long winded reply, but, YES, use 303!

The Dodger on my boat is not torn it's quite intact however when gets wet it water just really runs through the top like an old fashioned canvas tent will
303 even slow down that kind of water penetration?

It worked on our Bimini very well. Whenever the water started coming through, retreatment made it good as ever.
