Thanks Robert...great write-up and helpful to a new welder like me.
I know there are issues with lapping joints (someone here called them 'rust generators?'), but I am so low on the learning curve right now that my panel fitment skills required at least part of the new metal done that way to help me align things.
When I start developing more skills at this, I want to understand what's going on with the welds and metal and gaps and methodology. Then I can go back and repair all the ugly I am currently putting my truck through.
I have a small Lincoln MIG welder that I had been using flux core wire with up until recently. Then I tried gas and solid wire and LOVED the difference it made. So, I am making some progress, but it is slow going. I wish I could retire for a while and come apprentice with you in your shop!
Thanks for taking to time to explain all this. I very much appreciate it.
