Do not use alone as a lube between metal surfaces.
When I was looking for a good description I found a dodgy web sight that recommends gun oil for other games so I have left it on !!
What makes Gun Oil Silicone Lubricant extra special? Well, Gun Oil's ultra concentrated silicone formula is longer lasting and keeps you well lubricated. The vitamin E and aloe vera minimizes skin irritation while provides restorative properties. Gun Oil Silicone based lubricant is hypoallergenic and goes long and string without breaking down or drying out. Perfect as a fisting lubricant and anal play!
Gun Oil is actually oil free so it is completely safe to use with condoms.
