Hello! Very excited

just got myself a Ribeye A600 with an F115 with 300hr on. Been boatless for two years, have been begging and borrowing after the boat yard sank my last boat! Going to be keeping the boat in South Cornwall and Brighton. The trailer that was with it was dead so waiting on a new trailer that should be ready in two weeks.
Any recommendations as to what to treat my new trailer with? It's going to be going in and out of the sea a fair bit, I will hosing the trailer down just as much as I can, but any recommendations for gunk that I can spray/paint the trailer with would be appreciated ...
