(18-4 step 9): Today
is alodine day. Most builders leave the tank interior bare, but
we're going the extra mile and alodining eveything. Maybe its
because of my history with rental aircraft and the amount of water I've
seen in the fuel system. It would be nice if I could say ours
will be "perfect" and never see water... but yeah right. So, like
most of the other primer choices on the plane, it's a peace of mind
thing. Plus, there's the added bonus that the alodine will help
the adheasion of the proseal.

One
thing unique for us about the tanks is we're alodining the skins.
We haven't done this yet, so it was something new to figure out.
I tried the "brush on" method by laying the skin on our screen door we
use for priming. The challenge is keeping the skin wet while
keeping yourself dry. All in all, it was a little challenging
maneuvering the skins with the winds. But, it's all done now!

In
hindsight, if we were to alodine skins again, I may search for another
method, or at least technique. The results were barely acceptable
(by my standards at least). The surface treatment is VERY uneven,
which by itself is fine, but some areas appear as if they weren't
touched at all.
