Rust can be an evasive foe. I remember finding small rust specks poking their heads just barely above the paint's surface. After exploring, I found that the rust had spawned deep below and festered its way up. What appears as "not too bad" can often become a learning experience such as yours. You will do fine welding in those patch panels and will gain valuable experience in doing so. Besides, nothing can compare to the intrinsic feeling of acomplishment that one earns from doing a project such as this. Take your time, learn, and most important, enjoy the experience.
