Non-roof use of IWS

The roofer used Stormguard on the eaves and valleys of my house. No problems with the roof. I was impressed with the Stormguard.

I have a galvanized metal rainwater tank that has a few leaks. No squirters; just seeps. I've emptied the tank and it is bone dry inside. Metal still looks new; no rust. This is smooth not corrugated. Panel seams are exterior.

All the instructions I find for IWS says to install over wood substrate. Is it possible to use IWS to line the inside of my tank? I'm convinced it will hold water fine while the tank is full. My worry is it might peel off when the water level is low and there is no pressure holding it against the tank wall. Will it adhere to the metal? Are there better/more sticky brands? Different material that might work better?

Yes, I know I can buy a tank liner. They are expensive, almost as much as a new tank. Thanks for your comments.

I don't think I&W would work very well,IMO.Why not try and find the leak and silicone it?Or blueskin would probably do the trick

What are you using the rain water for? Drinking, Pets, Garden if so I personally would not use it because it could leach out gases and toxins into the water.

the water will leach toxins from the ice shield that will kill the fish,dry the tank out,place it outside in a well ventilated area,and seal those seams with GEOCELL 2300 tripolymer clear sealant,leave it outside for 2 days so it dries and cures fully,before bringing it back in the house and filling it with water
should work great
