If you are building any of the die-cast metal large scale models out there, you are probably familiar with the pain around driving screws into metal parts. In my experience, some of these screws have a tendency to bind up, strip threads, or simply snap off. Not only does it cause frustration, but it could cause a long delay in your build waiting for replacement parts.
For a while now, I have read about other builders that were using a little oil on their metal screw threads to help reduce the risk of damage and the effort needed to seat these screws fully. Up until this point, I had taken my time to carefully pre-thread metal screws, but it turns out they were on to something. I recently picked up some 3-in-One Multi-Purpose Oil (from the WD-40 Company) and it has changed everything!
I simply dip the tip of each metal screw into a tiny drop of this stuff and they go right in and without any drama. I should have done this sooner! If putting a little oil on the end of a metal screw is not feasible, you can also use a toothpick or other small tool to apply the oil directly into a screw hole before installing the screw.
I highly recommend grabbing a bottle of this oil (or other similar lubricant). It will surely save you time and headache!
