Ahhh, it makes sense that marine supply is probably the answer for getting the stuff cheaply. I can understand the need with the corrosion that salt water creates.
I'm inland, and it seems that few people know of the stuff. Except for the tractor supply (and the expensive chemical suppliers), I only found one other place that carried it in 8 oz. continers! On the next trip to Florida I'll stock up.
Thanks for the advice!
