Do I need to take all the studs and the power-valve out before I send it?

When we process cylinders, we usually need to immerse the whole thing in some strong chemicals that will attack materials like steel, brass and so on. Because of that, we like to have all of those materials removed before we start work. Sometimes, parts are cast into place during the manufacturing process and they are impossible to remove. In that case, we will paint a protective lacquer on those parts to try to prevent any chemical attack. YOU MUST UNDERSTAND that while we take all reasonable steps to avoid damaging parts when we process cylinders, we will not accept any responsibility for any damage that does occur. If any parts are not removed before the cylinders are sent to us, we may have to make a charge for removal.
