Hello, I know it's been cover before a few times, but ...... I have a tank that has been previously repaired (a small hole soldered) but has recently a fuel stain has started to appear. What I'm wondering is what is the best method for making the tank safe to re-work the repair. I was planning on resoldering the hole. Secondly I know people have mentioned treatments for inside the tank. Are these treatments for repairing rust, or can it also aid in stopping leaks? the tank is from my ute but I know the same discussion has been in here a few times. __ Cheers The Happy Drunk K100RT
