I have an old John Bean G-200TR orchard sprayer, 300 gallon. Where the tank was welded to the frame, the tank has corroded. The previous owner had some sort of patch over the rust holes but they started to fail. The tank is approx 1/8 inch steel and the inside was zinc coated. I am dealing with rust areas about 3 inches by 5 inches (or less). Some of the rusted metal is jagged and sticking into the tank, so the surface is not very smooth. Does anyone have any experience patching holes like this? I am able to climb inside the tank to get to them. I know the best option is to remove the tank and have new metal welded in, but that is going to be a time consuming fairly expensive option. I am looking for something reasonable inexpensive I can patch the holes with that will also be water tight. I had each hole sandblasted to see what I am working with. I can probably hammer each of the holes somewhat smooth with little effort.
One product that I am pretty sure will work is called a Zip-patch made by a company called Devcon. Problem is each patch is $50. Any other suggestions?
Thanks.
