Hey there, I'm fixing some rust holes in my datto and have cut some neat square holes to remove it, then applied rust converter. I was going to hire a welder and weld up the holes with some metal. But before I do, what things have other people done other that welding and stuffing around with cutting metal to size and hiring a welder, is there some other way to do it so it lasts a long time? I did bog last time but it only lasted 2 years. Cheers
