In order to keep your boat looking “just detailed” it is important to clean it yourself periodically between professional detailing’s. The sun is very harsh and can do a lot of damage if you do not take precautions in order to protect against. It doesn’t take much to have water stains build up and even etch into your vinyl. My recommended product of choice is 303 Aerospace protectant which can be purchased online or at most home improvement stores. You can really preserve the life of your vinyl and keep your seats looking newer longer with any protectant. Wipe down all vinyl surfaces after your outing and then apply 303 or your choice protectant, for a long lasting protection. Your boat is one of your top 3 investments, take care it.
