Polishing zinc metallized cylinders

Dear Sir

The current procedure to refurbish LPG cylinders is shotblasting and zinc metallizing, using an electric metal ADC system. The finish from this is coarse and pourous, the cylinders is then sprayed with an aluminum paint, to seal and finish it. We have found that if we submerge the cylinder in a ceramic ball mill for 10-15 min, after metallizing, the zinc coating gets a smooth polished finish that does not require painting. The problem we faced with this process the difficulty in keeping the cylinder submerged. It is not practical to fill each cylinder with water in order to submerge them. We are looking for system that can achieve this more effectively.
