Questions: Dry systems or wet?
If dry system what type of seals? Can you identify the lubricant (i.e.: vegetable shortening, manufacturer's recommended product, petroleum based product)? Actually foaming (i.e.: expanding and looking like shaving cream or a slightly more aerated product from an aerosol can)? Is there just an over abundance of lubricant at the joints/ Is it dripping? Does it occur all year or only during warmer days?
