My wife and I purchased new kayaks in the spring...and Id like to keep them looking that way for as long as possible. Im very diligent about rinsing and washing the salt and sea scum off of them, but was wondering what the rest of you do to keep your boats shiny and new looking, and also to keep the rudder movement like new? Is armorall a good idea for the deck? Is WD40 a good/bad idea for rudder movement? I have thermoplastic Delta boat, and my wife has glass Necky. Thanks!
