keep your gear fresh — a few simple habits
rinse after every surf. fresh water. a 60-second rinse saves gear for years.
dry in the shade, store cool. direct hot sun can delaminate darker boards. keep boards in their cover, flat or on racks — leaning on soft fins can warp them.
check your leash & fins often. look at the swivel, string and plug screws. a tired leash or a loose fin will ruin a good wave and can cost a lot more than a wipeout.
wax it right. base coat first, then top coat in small circles. when it gets grubby, strip it off with a wax comb (or park in the sun for 10 min) and start fresh.
