boat repair and the river

[mikota40]

I am about to seal up my 14" aluminum boat to take on the upper potomac. from what I see on some of the boat forums a product called gluvit is near perfect for sealing small alum boats. it costs more than your house! its 50 for a quart . has anyone used this stuff around here? where did you buy it? howd it work for you?

I have a 14 and 16 foot aluminum and never sealed either one in 35 and 40 years of use. Neither leak.
