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?
