[VACList] Boeshield T-9

["T Meeker" <tmeeker@xxxxxxxxxxxxxxx>]

Jim,

Here's what Boeing says about Boeshield T-9.  They don't mention using this
product as a replacement for waxing aluminum *but* it does leave a waxy film
after it dries.  Note: you may have to redo the material again in possibly
3-5 years. ;)

Once on the surface, Boeshield T-9* has excellent penetrating and moisture
displacing properties. Using capillary action it will cut through and stop
existing corrosion, find its way into lap joints, seams, and around rivets,
and eventually weep out the exterior. However, this activity stops after a
limited time (usually 5 to 7 days, depending on temperature and humidity) at
which point a waxy film develops in all areas. In this way, the coating will
stay put for much longer than the all liquid treatments, eliminating the
continual weepage and cosmetic problems associated with them.

When reapplication is necessary (usually 3-5 years depending on service and
exposure) the existing coating will be re-liquefied and resume its
penetration and weepage, again only for a limited period.

Boeshield T-9* also is non-conductive and will not cause short circuits in
electrical systems. However, care must be taken to keep away from areas
where point contact is required, such as keypads on electronics.

As mentioned previously, Boeshield T-9* has a mineral spirit base and
contains no harsh solvents such as MEK or Trichlor Ethylene. Therefore, it
is safe to use around most paints, plastics, rubber, vinyls, wiring, and
many glues. It is very effective for rust proofing steel tubing on fabric
covered aircraft, but should be tested on the exterior skin prior to
application to insure no degradation of the material or lap joints takes
place.
