Hey Jamie, Never tried it, you havn't got much of an alternative , araldite is also worth a try,and might just get you out of trouble for a short term fix.
Don't use a tank liner for that it will leak again,as well, needs to be welded/soldered, there is alot of stress on that hinge
When you come to get it fixed permanent, Brian W had his tank soldered /brazed up and didn't even need to get the tank resprayed,
By the Guys at Dmoto, they had a guy that could do it, give them a call
