I noticed on my Hustler aluminum gas tank that there is a leak, which I believe is coming from where it is welded. Does anyone know if there is any sort of thing (such as a sealer) that I could put on there that would stick to aluminum and be resistant to the gas? The aluminum is really thin and I wouldnt want to weld it because I'm afriad that it would burn right through and I am not very good at welding aluminum either. Any help would be appreciated. Thanks.
