More time consuming than spray, but, its produces zero fling/mess.
2 full squeezes for re-application. 3 for a clean chain.
Unscrew the brush to apply. Its also easier to reach the difficult to reach inside (wheel side) plates.
Highly recommend:)
I found this as a yearly procedure: Check air-cut off valve, reed valve.
Looking at the service manual its seems quite a specialist job for an annual check?
Your thoughts, please.
