I picked up a cheap (made in China) hammer and dolly set from a big tool store in Hayward, CA. I think Harbor Freight carries something similar.
Very very nice work indeed. For the tools and primer and such, what sources did you use?
You should use self-etching primer against the bare metal. Use high-build primer on top of that for smoothing out the bumps and filling in any minor depressions.
Also, does any old auto primer work?
