I've been busy with other things, but have made a little bit more progress. I put another patch in right behind the very first one I made. Remember I said I didn't cut enough rust away? Well I noticed another rust hole behind the first patch so I cut more out and put this patch in.
A little bit of grinding gets those welds down. I've also been shooting ALL bare metal with that rusty metal primer as I go along. It has been rainy here lately and the humidity has been horribly high. I noticed surface rust everywhere I had left, even just overnight. Now it all gets a shot of primer before I'm done for the day.
The big long open strip is the next thing to be welded up.
