Joel, do this:

Identify your AFM.

Take a utility knife, and carefully cut the factory seal that goes right
around the lid of it.

Using a flat-blade screwdriver, carefully and slowly pry off said lid,
beginning at a corner.

Spray electronic cleaner (Radio Shack or FLAPS) onto resistive surface, and
move wiper a couple or three times etc.

Let evaporate, don't touch it with a cloth as you don't want fibres in there
or other contaminants.

Remove old silicone seal from lid (tedious) with a knife.

Close lid, seal right around with a good tape.

*** Since I've done that, my WESTY has not bucked once!
