Actually it’s fine for filling in small dents and a few pin holes, but in my case I was just experimenting with a junk gas tank. I never intended to actually use this gas tank ever again because it is too far gone with rust. And using too much lead adds a crazy amount of weight to it as well. I actually much prefer silver solder to fill small pin holes or cracks with a small butane torch and silver solder. Maybe I will make a video on it someday. Thanks for watching and your comment. Take care my friend.
