Cleaned a Saladin petrol tank (LHR) and discovered half a dozen pin holes (under the hydraulic oil tank so I guess rusted from outside in, rather than the reverse). I have a POR-15 kit to clean, derust and reseal the inside, and the kit includes a patch for holes but I'm a bit wary of relying on that. So, my plan was to fill the holes with solder then perhaps solder a plate over the area. The affected area is around 3" across.
However while someone told me to use silver solder, a plumber told me today that silver solder isn't for steel and that I should use normal solder. What should I use?
Or, would it be better to MIG weld a patch on? And if I go with welding, could I also plug the pin holes with that, or would I just blow bigger holes in the tank? (You can see I'm not an expert with either welding or soldering!)
Whatever I do, I'll put the POR-15 patch on top of it.
