Exactly. Plastic watering thingies are not expensive, keep one for particular purposes (watering, weedkiller, herbicide). My neighbour used weld galvanised steel into trailers. I warned him that zinc fumes were at best poisonous. Cancer killed him. I would see him late at night, welding, with fumes rising, like a sorcerer. Unless you wirebrushed well back to what? 22 steel?..
D-i-y, that is use "oogoo", which is homemade sugru.
It's acetic acid silicone sealant, with cornstarch added to make a paste. Or two drops of gylcerin. (Apparently the original was first made using wood dust...)

A bit of wire brushing exposed a small hole. At first I fixed it with Araldite; this worked for a few years, but it eventually failed. My second attempt was with SUPER STEEL; this worked for a few more years; but it eventually failed. So I decided to research a soldering solution. This is what I found:
*** Use lead/tin 60:40 solder *** Use "killed spirits" flux *** Use a tin plate patchKilled spirit was made by dissolving zinc in concentrated hydrochloric acid. The internet helped with the details. The tin plate patch was easily crafted from a tin can.
The watering can base and back of patch was cleaned. Both surfaces were painted will killed spirit and then tinned with the solder. The patch was held in place, heated and extra solder added.
The result was a very workable patch (see photos)
