my 14' jon boat leaks from the rivets i presume... i used some boat sealer stuff from walmart on the fron parts of the boat and seems to have worked... but there is still a pretty constant leek that just gets to be annoying because i have to keep using the bilge to empty it out... is there some specific type of sealant and technique i should use that is compatible with aluminum...<br /><br />from what i gather from some of the websites, i should flip the boat over, clean it off, cover entire boat with sealant, then let cure then paint... and this would stop all leaks???<br /><br />and where you buy the sealant would help me too...<br /><br />thanks in advance for any help you can give.
