Lube the Stabilizer Housing
The most important part to lube is inside the stabilizer housing. Get a brush and work the lube into middle of the housing, this will improve how smoothly the stabilizer actuate. Avoid lubing the outside of the housing, as it can make a nightmare of a mess.
Should you lube stabilizers? Short answer: yes! Lubing your stabilizers is much much easier than lubing your switches and you can feel the difference right away. You'll notice how much better they sound and feel. While you're at it, we also recommend you look into clipping and band-aid modding your stabilizers.
