QuickSteel [which that looks like] is easier to form than JB Weld, but it seems to crack and come apart easier than JB weld. Especially when using with plastic. I think your attempt is valid, you will just have to see how well it goes. For a $320 dollar savings I would at least give it a try or two.....
