P&C repairs on Sukaphibaan 2, they did a good job (crash repair) a few years ago for us. We used one on Sukaphibaan3 and it wasn't nearly as good. If you were coming from minburi direction pass the outer ring road, pass the new (ish) petrol station, pass toyota and it's on the left hand side about 300 meters passed toyota. Not sure if they do rust, but there nice guys and professional.
