Paul,
I am working on the plane. Using Alumiprep, Alodine and the Variprime.
The alumiprep look like it should, but the Alodine is failing to turn
the parts gold toned. I just bought the bottle....
Any ideas?

The aluminum is not anodized is it?
Did you acid etch it first before Alodine.
What alloy is it?

Blake, What's the temperature of the Alodine,  I use Alumiprep also
works great even in cool temperatures. However the Alodine needs to be
warm at least 65 to 75 F to be active.  Then it takes only 3 to 5
minutes to coat the parts.  Did you dilute the Alodine from the bottle?
I believe the ratio is 2:1 Alodine to water. Matter of fact did some
Alodining  last night the temp of the mix was 68 when I started and 65
when I finished.  Parts came out just fine. Regards T.W.

   I will check my temperatures next time. My shop is heated, but I
was venting cold air into it to help with the fumes. I was comfortable
in a long sleeve t-shirt though. It was 31F outside. The radiant floor
heat I installed in the shop is so comfortable. everything stays so
warm to the touch. I went ahead and painted everything with VariPrime.
