Qa-1 coil overs leaking

[Amack1970]

Has anyone noticed there front coils wet with oil around the dampening adjuster? I took these pictures after washing my gob, and there still wet. Any thoughts? What's the model number of these coils, warranty? Not sure what direction to go

If a shock bottoms out is can cause it to go bad, for extra protection I added bumpstops to the shafts of my QA1's. The BC rears have bumpstops under the dust boots. The piston on my QA1 was 16mm. Pictures here :
