Where are you using it?


The leading edge of the ailerons is thin alluminum sheet. I put a lot
of effort into physically removing corrosion on the left aileron and if
the right was in the same shape, I was thinking it would be easier to
simply make new parts. Someone pointed out that alodining chemicals
could be brushed on (rather than having to build tanks) and cost was
very reasonable, so I think I'll stick with my original approach. The
sheetmetal will be covered by fabric.

By the way... There is a metal prep that is used for cleaning prior to
alodining. It is a phosphoric solution. Is that also used for
chemically removing corrosion, or simply preping the surface for the
chromic coating? - Mike
