I want to add lubricating doors and windows as an add-on service.
If you do this service now, how can I educate myself more on this?
What lubricant do you use Boeshield or other?
Where can someone learn how to lubricate the more complex doors like the 5 point pin locking?
What is a reasonable charge per crank out window? Door hinge and locking? Double hung?
I use white lithium grease. I get mine in a small tube almost like a mini caulking gun. I feel like I can get where I want with little to no clean up. I usually find in the gun shops next to the gun cleaner.
