Chapter 20A Surface Finishing
The following pictures deal with the surface preparation for paint. This entailed micro...Sanding.....multiple layers of clear coats of pure epoxy....followed by a high build primer ...and more sanding.
This chapter and pictures are in the process of re-construction....;)
This is the high build primer that I chose to use. After sanding the aircraft down with the micro slurry. I clear coated with pure epoxy, roughed it up a bit and then applied this 2 part epoxy high build primer to the aircraft. I then sanded that down in preparation for the final paint that is shown in Chapter 20B.
I first started using Aeropoxy Light but found that dry Micro worked better so switched to that. So the sanding began.
On the wings I would spatula on a layer of micro of peanut butter consistently. Then I began using the "board of pain".
I logged many a hour sanding the surfaces to a nice smoothness.
More sanding, Used a dust mask during most of this task.
After achieving the smooth surface. I squeegeed on a few thin layers of pure epoxy to "clear coat the wing. This gets most if not all of the small pin holes.
Another before and after shot.
I used the same procedure on the canard as well as the whole aircraft.
The upper and lower strakes.
The fuselage also go the treatment.
I then roughed up the clear coat a bit and applied the 2 part epoxy high build primer that is shown in the first pictures of this construction chapter.
After cure, the sanding process started all over again.
Part of the process also envolves flipping over the fuselage. This is a big job and requires the construction of 2 large wooden holf-circles that are bolted onto the main spar.
And more sanding the primer.....
The fuselage is about ready for painting....finally
Pushing the fuselage out of the garage to be prepped for the painting process....
SEE Chapter 20B that covers the painting.
