I have some couplers which are a little "stubborn" closing - I need to add a little "0-5-0" to the rear of the car I'k trying co couple to. I've searched the suggestions on the forum, and one of the recommendations I see is applying graphite to reduce the sliding friction.
I'm wondering if anyone has tried neolube liquid graphite lubricant and, if so, did it help and do you recommend it?
If you really want the couplers to work easily, it's likely that you'll have to take them apart and smooth all the interior latching surfaces. I've done this to a few, and they close really smoothly with almost zero pressure. The molding "flash" on them and the rough surfaces on the latching surfaces is hard to fix with just lubricant.
