Seems the Pushmatics dont fare well much anywhere! Corrosion is an issue with most everything
when you get close enough to the ocean... (I've changed 3 panels on Oceanfront walk in Newport Beach, All rusted out, holes & all... One was a pushmatic... Lots of Noalox on the bus & lugs helps to at least get out of the warranty period before nature has her way with the new stuff!)
You ain't kidding about the sand either... with the vents in the bottom of the breakers, they seem to attract sand something fierce! Especially in our Inland Empire & desert areas... (The 909 to the locals
) vegetation is typically minimal there... Ive pulled pushmatics out of a panel in Colton & it was like a salt shaker!
