What I can recommend from experience
is limited by the regionally available brands. Having said that if you can get Sherwin-williams Industrial machinery enamel that would be my first choice. That is VOC compliant and so is nice to use in small spaces but use a fan. Go to you local company paint stores and look for industrial enamel such as is used for outdoor structures, tanks, chemical plants, bridges, fire escapes etc. Some of the ZEP brand cleaners are very effective when applied with some elbow grease. Again the paint dealer can recommend what is best in your area.
