There are two kinds of 303. You have the vinyl dressing and then you have the 303 Fabric Protector. That's what many auto manufacturers put on canvas auto convertible tops.
You want to use the 303 Fabric Protector that's also available in most marine dealerships.
yes, I know thats what I use ( fabric ) and iuse the other as a touch up between polishes ( the hull ). I've used 303 products for almost 10 yrs now. I mean other brands or home made brews
