If the anodised phlogiston spars (used
on RV's) have half the fatigue life of an alodined spar


My newsreader doesn't get all the messages, so I may have missed the
antecedent referenced -- but what's the source that the anodized spars
have half the fatigue life? and why? Is that true in general, or only
for these spars?

thanks
