I bead blasted my Eldo cases but only after removing all the guts. Even
then, it is critical to rinse and rerinse and inspect all holes,
threaded or not for stray particles. Don't ignore any surface. Very
risky but very pretty when done. Once assembled, I soaked a clean rag in
WD40 and wiped it all down. Did the same to trans and rear drive.
They've been sitting out in the Doghouse for months now waiting
assembly. Not a speck of oxidation and believe me North Central Florida
is the king of oxidation environments. It and rust and mold can come on
in mere hours. Smaller pieces that do not come in contact with gas and
oil (well...theoretically) have been coated with Nyalic from Eastwood.
I've used this before on the G5 with good success.
So many methods available, aren't there? I suppose they all work to one
degree or another and local conditions certainly have an impact. By the
way, I think it was during a similar discussion on this list a while
back, someone mentioned a company that makes aluminum cleaner for
aircraft. I'm not in the shop right now so don't have it handy, but that
stuff really works! Requires lots of elbow grease and patience but
initial results are immediate and if you keep going, it's amazing. I did
the trans and rear drive with this juice. Not as bright as the engine
but really, really clean.
My G5 wasn't a pretty bike, although it did take 2 trophies at the
Volusia County Fairgrounds at Euro Day during Bike Weeks past, but I
didn't show much concern on a regular basis for its cosmetics. The first
or second time I rode to the Blue Ridge rally many years ago, I met Bozo
on his Eldo. This was a classic example of a rat bike but mechanically
very sound. Every time he would go out for a ride he wiped down the
motor with an oil soaked rag when he came back. I ended up adopting this
method on the G5 for a year or two, then gave it up out of laziness and
having burned my hands on the exhaust more than once. Just another
interesting method.
Anyway, to echo Mark, be very careful with the abrasives. If you won't
take the time and care to inspect and clean multiple times, don't use
them.
