Re: Off season bimini maintenance question
Remember that you have to apply 303 Fabric Guard on clean, absolutely dry Sunbrella. The manufacturer also suggests spraying the fabric under a hot sun so it dries properly. I have found that you need to spray a few coats to get the fabric really waterproof. I gave my bimini a good saturating spray with 303 in the sun and followed up with 2 more light mistings (weeks later) to get it fully waterproof.
