I/S frame protection

[Aribert_Neumann@magna.on.ca]

I am looking for a wax type of a product for corrosion protection inside of a
frame. I remember seeing Waxoil (?) advertised somewhere.  To the list in
general, what product(s) are you using on the inside of a frame?  I have an
undercoating gun (J.C. Whitney, same as Eastwood) to apply the product.  The
frame is for my next winter (non LBC) vehicle and will be used where road salt
is actively used.
