Brief Description: deburred the LG box Assemblies
|
|
I deburred the previous parts for the landing gear boxes but more importantly - I made a decision on the next primer step. If you haven't noticed, I have been working the parts up to the point of "Prime if/as desired" and then skipping to the next set of parts...this has been necessary while I continue my inner debate on which way to go with the primer. For the empennage and the wings I was fine with using the self etching, rattle can primer because those are primed on the internal structures and do not see any use - like hands and feet or even eyes. The fuselage is in more of a hostile environment with people climbing in and out, hands, feet, pens, seat belts, headsets, drinks, sunlight, etc. taking their toll. As such, I need a more durable finish. I have read a bunch of opinions and talked to a lot of people and have heard all inputs from "no primer, no nothing" to two part epoxy primer and top coat. I decided on the Stewart Systems etch (to prepare the aluminum) followed by the Stewart Sytems Ekoprime and then for the parts that are visible/under duress a topcoat of Ekopoly. I also decided to go with the smoke grey color - a light grey.
The primer is a non-toxic, non-flammable product that when cured stands up to fuel spills, lacquer thinner and MEK. The top coat is a solvent based product and, as a bonus - it passed the penguin poop test!
