after looking around and reading up on some things... sounds like the only
prevention is either replacing EVERY thing aluminum with stainless
steal...or... get an air cooled van haha (just kidding)...because depending
on exactly what materials the rubber has in it. ... if it has high content
of carbon OR epichlorahydrin (which has HIGH amounts of chlorine) ... mixed
with small amounts of water that get in and the aluminum oxide powder (aka
ceramic) layer aluminum produces to help protect from oxidation it creates a
hydrochloric acid that will ultimately corrode the aluminum... not to
mention climate and the amount of salt water that may be in the air (like if
you live near the coast or where they salt the roads)
i think its just one of those things that unless you go to ridiculous
extents... is just a fact of life...i dont know ... i dug pretty deep for
that ...
if you find something out about this let me know ... its going to bug me
now ;)
