Re: Skid Plate for 20 Gal. steel gas tank?
One of the concerns I have is that if it's got one pin hole, more aren't far behind. So, by repairing the tank you might be dismayed to find more pin holes to follow in short order. In fact, the welding of the tank will stretch/contract the surrounding metal, and may cause a few more holes to open. That's not to say you shouldn't do it. By doing the repair you'll buy time.
Steel tanks benefit from good priming and painting. This seals the outside of the tank from the elements. The inside of the tank is often forgotten. This is an oversight that bites one in the butt many miles down the road.
After repairing the tank it's not a bad idea to make sure it's coated on the inside. This prevents corrosive action from penetrating the steel and starting the pin holes. It also will help seal those areas that may now be developing into new pin holes.
The POR people make a good tank coating, as does Eastwood Products and about a thousand other manufactures.
