Waxoyl vs. Other stuff

["Dan Ray" <danray@bluegrass.net>]

Since Waxoyl is not available anywhere other than mail order for me, does
anyone have any suggestions for a suitable common alternative? Waxoyl is
pretty expensive, and I've learned that only SOMETIMES do you get what you
pay for.
I see a lot of spray-type rubberized undercoatings. Anyone tried these? I
wanna KEEP my car rust free and it really needs something in the nooks and
crannies!
TIA
