There is a lot of rust inside and after couple washes with a hose (w/ some applied pressure) little flakes started falling off. Then I noticed that there are small leaks on the seam where two metals come together. I though of stripping the tank off of paint and doing a welding job on it but with the gasoline fumes it is definitely not safe. Is there any way to avoid buying a new tank and saving this one. Also, how do I take the rust out. I know of the bolts and nuts way and the special treatment for rust but are there any other cheaper alternatives that would work?
