With all the recent rain here and some new res accounts I broke out the old Lawboy S21ZSR because it is light weight and can side discharge. Problem is it has a pin hole leak in the gas tank and it costs $65 for a new tank. I can get a new tank but thought I'd try a cheaper route first. Has anyone had any luck using a sealant or plastic weld on a plastic gas tank? I have thought about getting an aftermarket tank like what was on the heavy duty LB's.
