Hi MGT Types,
You may remember the saga of my new TF body clad in aluminium alloy rather
that steel, and the response I had through the List on the subject of
dis-similar metals being in close contact and the possibility of subsequent
corrosion .
Well my friend Colin Gibson put me in touch with an Aircraft Engineer Peter
Tanulac, who made the following recommendations. That all mating parts ( ie
Ally/ steel) be coated with a paint called Duralac, which is used is similar
situations on light aircraft. Where POP rivets are used employ ally rivets.
He also advised the use of a Lead sacraficial annode approx 75 x 25 x 12mm )
and attached to the bare ally body( ie metal to metal contact ) and finished
with a wash/ etch primer. The annode is renewed when it disappears ,
probably in the after life!!!!!!!.
My considered opinion is that if it it good enough to fly in it is good
enough to ride in, and this is the proceedure to follow, ( unless you know
better ).
Keep MGing
David Tinker
