I only use the "popper" after trying whacking, pushing down on the piston to
help break the seal, and air pressure. If your are rebuilding the cylinder,
it is perfectly acceptable to use grease in it, with the caveat that it is
thoroughly cleaned out before reassembly with NEW rubber parts. I wipe most
of the grease out with a paper towel, then use simple green and water to
dissolve what is left. Then brake cleaner to remove anything else that
could cause a problem, especially to remove metal particles after honing.
With these steps, there is absolutely no grease left on the reusuable parts.
I would be much more concerned with something like using WD40 on a bleeder
nipple than using a grease gun to pop a stuck piston out. This is just my
opinion based on my experiences.
