Perhaps this Kester paste you have will do the trick. The standard Keter paste we had for soldiering copper you could get it on your skin with no adverse affects, the type you have sounds more caustic. All you can do is give it a try and see what happens.
Tin plate is very shiny and thin. Many of your wife's baking pans maybe made of thin tin plate with rolled wire edges. Sheet metal is galvanized, sheet iron with a zinc coating. All the duct work in your home is made from sheet metal which appears a dull silver in colour. Black flue pipes on your wood stove are not galvanized as the high heat burns off the galvanize and discolours it. So stove pipes are blackened and are of thicker min 24 ga. Sheet metal is not food grade acceptable since the galvanising is affected by heat and I am sure the galvanized coating taints the food as well.
So do a test soldiered seam with this Kester paste as if it easily pulls apart.
