This stuff really works. It is mandatory
for making p-port rotor housings.

I made two test coupons out of 6061 T6 and bent them
after 24 hour cure. One was treated and one was not
treated. The JB Weld was thinned with a half teaspoon
of acetone per small tube package. The untreated aluminum
snapped apart with little or no force without bending the
coupon metal. I was able to bend the treated coupon no problem.
I'll run a shear test on the good  coupon later.

The West Systems preparation stuff is not alodine
as there is no colorization involved. I don't know
what it is but I think it is a caustic etch.

Merry Christmas.

Paul,

It looks like alodine.  Alodine can be clear or gold.  Most of the canard
guys alodine all of their aluminum parts for corrosion and adhesion when
burying them in the composite.

I always thought alodine had a greenish color.
