There are a few simple tools that can aid in finish welding the frame and component parts. Pictured below are the angle grinder with a flap disc, Drill with a wire wheel, a wire brush, slag hammer and pliers to cut the welding wire when necessary. A bright light can also help. I find that my welding greatly improves when I can see the weldment clearly.

I have finished priming and painting the suspension parts. They are glossy black.
