Quote: I tried using Dykem to see how well they were mating, but it just ran everywhere, so I ordered a tube of “prussian blue” last night. 
I recently bought a tube of prussian blue for checking fits on gun parts. I learned very quickly to wear gloves when using that stuff. One little drop on your finger and it ends up on everything and anything! It’s like anti seize on steroids!
