I apologize if this ends up as a duplicate posting. I have been fighting a DNS problem with Comcast for the last hour and finally had to sign on to my neighbor's WiFi and type it all over again.

I have two tanks that we dropped here and now I will be taking them to Pro-strip to remove all of the outside rust. They put them in a tank large enough for an entire car and soak them to remove the rust chemically. The insides are perfect but wire brushing the bottom outside we opened up some small holes rusted from the outside in.

So now the question is how to patch the holes:

1. I found a product called Water Weld made by JB Weld. It can be applied to wet surfaces and even below the water line in water marine applications. It also can be used on wet / leaking gas tanks. I called them and they say it is definitely applicable for sealing tanks. Since these tanks will come back perfectly clean outside and in, I think this would work very well and could be sanded, ground off fairly flat. After that I intend to paint them with POR-15 and top coat with white or silver rustoleum.

I am looking for opinions from anyone that has used the Water Weld product is product.
