Oops - crud - how did I miss the Canada part... sorry about that! Where are you at in Canada? What was the drylock cost? Down here its about $25 a gallon.
i'm in quebec, which has funny laws about stuff... and i think drylok is 36$ a gallon at canadian tire. home depot and rona don't seem to sell it. would a gallon be enough to give the tank multiple coats?
i am coming down to the states for the day this weekend, so i might be able to pick some up when i come.
