I have my welder set up now, so it welds well every time, even with C02 gas. I have found one of the things that influences how well a panel goes in is the ammount of preparation that you put into the panel first. If it fits well, and is clean, it will go in nicely. I have tried to use weld-through zinc primer where ever possible so hold off the rust as long as possible.
Anyway, pictures tell a thousand words, so here they are..
Once I have done all the welding I can with the car in its current position, I will need to lift it up of its chassis, and be placed on some stands. This will allow me to get under it and finish of the underside.
