C&C 30 Mk I came with a nice Genco bimini/dodger/connector. Some accumulated dirt in the seams and corners - gave it a scrub on the back deck with soap and water, then applied the 303 protectant. This stuff is expensive, and you need to hold the bottle back far enough from the material to let the spray disperse, otherwise you will go through it pretty quickly. Good performance after one season of use, no leaks, but it certainly does not bead water - was expecting a somewhat more repellant coating. Will repeat next year, and also apply to UV shield on the roller-furling genoa in the spring.
