That's correct, there were a few reasons for wanting the trike gear, although the problems associated with trigear RVs do have me a little worried. An RV-4 has excellent vis in the three-point attitude due to the very narrow cowl - not sure how the 7 will be. With a self-etching rattle can primer, there is no alodine needed - just clean and spray. Should work fine for corrosion protection, especially over the layer of alclad already on the aluminum.
