This is a good time of the year to service your kayak. Stand it on a pair of trestles and give it a good wash down with hot soapy water, rinse well and dry completely. A bit of acetone on a clean dry cloth and wipe down the entire boat; this will remove any stubborn grime and old polish. Then use a good marine grade polish and apply liberally, polishing to a glow. Apply at least three coats for good protection.
Finally check all of your deck lines, toggles, RDF's, cockpit coaming, hatch covers and of course your trusty old skeg. Then apply saltwater, jump in and enjoy!!
