it only cost me $15 dollars. I found some places even charge like $10. They did the work on spot so I waited. I told them all I want is a mirror polish finish on my ody and pen. Not to do anything with inside only outside of the tank and upper cap and mouth piece. After they gave it to me I boiled it in hot water and re cleaned it. I made sure I didn't have any of that clay they use when they use power buffer.
