Alodining

I am getting ready to begin with my TSi that is a Quickbuild from the factory. The fuselage and the wings came alodined already. The other parts of the winges - ailerons, flap - and the empennage are not alodined. For consistency and for long-term corrosion resistance I am thinking I want to alodine the rest of the stuff.

Question: would it make sense to assemble the emennage parts and the ailerons and flaps and then dip them as whole pieces, or would one want to try to alodine the parts before assembly?

Disclaimer - I'm not alodining myself, just priming mating surfaces with self etching primer.
Also as far as I know, the factory does the same - it's greenish primer you see, not alodine.

That being said, if you wanted to Alodine, then yes, I think you would want to do all parts separately since you want the parts that will be touching to have equal coverage, which I don't think you could get if they were already riveted together.
Also I don't think you'd be able to make a big enough container to actually dip the entire Elevator or Horizontal Stabilizer, which are pretty large.

That's how to use a clothes line!

Are you using the Bonderite 33 and 1201 process?

Sorry for the tardy reply - didn't see the question. I use liquid Alodine from Aircraft Spruce and ToonBrite for prep. Steps are:
  • Take off protective film
    Relabel the part with label attached to fishing line.
    Use Acetone to remove any residual film adhesive
    Wash parts with Dawn to remove residual acetone
    Rinse in deionized water (I used one of those kits used for washing cars)
    Soak parts in ToonBrite for several minutes
    Rinse in deionized water
    Soak in Alodine for several minutes
    Rinse in deionized water
    Air dry

Interesting. I have never heard of ToonBrite. I'll have to try it sometime.

We are using the Bonderite process with 33 and 1001. I like the bright aluminum look of 1001 versus the bronze look of 1201.
