I have a 1985 lancer powersailer that is in great shape...but needs top deck refinishing. I have had quotes of 15k. I plan to use this boat for just about 3-5 years as an introductory to sailing (I am a newbie). There are no major problems with the deck except some surface cracks and discoloration. Is there a good sealing paint and method for a do-it-yourself job that will satisfy the short timeline and not cost me so much money?
