That could be valid reason.
The G84-4400 I got was from industrial environment, so fine dust might've entered with time.
G84-4100 after about half a year was still good. A guy I know has stomped on 4100 daily for, like, 10 years. I gave him one brand new lasered as a gift, just because he had the old pad printed legends worn out.
Still waiting for someone to report lubing results on ML.
As to comparing ML (low-profile) and Topre (full travel) - why?
