Have 40 foot wooden launch which has been extensively rebuilt. Most everything worked well except for the deck coating. New plywood decks (3/4" marine ply) sealed with Industrial Formulator's S1 Sealer (Canadian version of the magic epoxy sealer you hear so much about in this forum)and painted with two-part linear polyurethane paint. Supposed to last for a good long time. After two years the plywood is checking, particularly on the 'sunny' side of the boat. Gets worse after a summer rain. Obviously I need to do something soon. I reckon I have two choices: strip decks back to bare plywood and either sheath with cloth and epoxy, or do the thin-teak-planks-bedded-in-epoxy-goop thing. Would really like to hear from anyone who has done the teak in epoxy routine. Would also like to hear any other possible suggestions any of you may have. Right now I'm tempted to go out and buy a big bucket of rubber decking compound, a brush, a bucket of beer, and go to her! Maybe I should just stick with the bucket of beer for now. Thanks.
