[R-390] Gear lube suggestions

[chuck.rippel at cox.net]

This is easy and demonstrated in both the R390A and SP-600 videos.

Do not use petroleum based lubricants, for anything on the R390xx.  They 
will harden and you'll be doing it all over again.

Go to your local auto parts store or buy it off the net, a quart of 
Mobil 1 or AMSOIL 70W GEAR Lube.  Lubricate with that.  GEAR Lube, NOT 
motor oil, its too thin.
It does not harden and is very very slick.
