LPS products:

http://www.lpslabs.com/Products/Lubricants/LubricantsPenetrants.asp

or http://snipurl.com/fdtj

FrameSaver available lots of places (ex:
http://www.branfordbike.com/bikecare/bcare1.html#item3 )

Quoting from http://www.vintage-trek.com/refurbish.htm :

INTERNAL RUSTPROOFING OF A FRAME
Unlike some other frame materials, a steel frame does not degrade
through normal use or simply through age. However, if a steel bike is
ridden in the rain or is kept outdoors, rust in the inside surfaces of
the frame tubing can be a problem. A way to check if your frame has
been damaged by rust is to remove the bottom bracket and look at the
bottom bracket shell and the tubes. Some rust is normal, but lots of
rust or significant pitting can be a problem.

To prevent, or significantly reduce, internal rusting, people spray
the inside of the tubes with a rust preventative. Two excellent
products are "Frame Saver" by J. Peter Weigle and "Boeshield T-9"
developed by Boeing. Frame Saver is available at most pro bike shops
and over the web. Which to use? Peter Weigle is a custom frame maker
(support a fellow bike guy). Boeing makes lots of great things, but I
believe bikes are not included . . .

A poor-man's solution is to spray the insides with WD-40 penetrating
oil. It dries to a thin, varnish-like coating that protects the metal.
Not as good as the two products above, but much better than nothing at
all. (BTW - because of this drying characteristic, WD-40 should not be
used as a long-term lubricant.)

Better link for the LPS-3:

hhmmmmm!
the stuff mentioned is no better than rusto's mail box saver.
the stuff is a temporary fix while you getb your act together to take
the frame to a professional metal guy and have the tubes stripped clean
with caustic and boiling water
then immediatedly painted with a pro primer.
the mail box saver is a phosphate treatment (for steel boats where
using the dremel and hand pick tends to be inconvieneint) that produces
a skim of non rust over the rust then adds latex as an impermeable
vapor barrier (like alkyd but without the oil based layer) but ponder
latex is waterborn-gives rust with O2)
the rusto works but its temporary. i ssume the weigle is similar.
linseed oil thinned then covered with white farm rusto thinned works
better than the rusto mail box saver. phosphate straight then rinsed
with boiling water... its gets complicated.
a pro knows!!
 
for the linseed-need to do this on a hot day allowing the frame to cook
water out.
gotta let the linseed dry before appllying the farm rusto. farm rusto
is better than consumer no patience rusto. the manure spreader gets
paint then is allowed to sit under the sun to dry
until august
 
ima talking to muhself agin.
the deal with the quick fix is do you trust or believe whyjell's intent
to sell the stuuf YOU NEED IN A CAN????
or to make a profit selling stuff to you in a can.
like what in tarnation could wyejell put in a can that yawl can't pour
in urself?
like i wuz looking for very finely ground zinc powder to ix into the
thinned linseed.
you name it.

Please don't misconstrue the silence.

Our reverence leaves us speechless.

Preach, Gene, PREACH!
