I decided to test out the SEM Primer and Prekote on a few of the Horizontal parts before I went ahead with priming all the Horizontal parts. I also couldn’t figure out the best way to keep the Left and Right side parts seperate, so I only took home the easily identifiable parts (like HS810 and HS814) along with the Left side parts (Spar, Ribs, etc).
For the Prekote process, I sprayed the parts liberally and hit them with the scotchbrite pad again. Once that step was complete, I rinsed them with the hose into a bucket. I then took and sprayed Prekote on all parts a second time, and once again rinsed them in the bucket. I let them dry completely and then sprayed them with the SEM Primer. Below is a photo of the parts I tested with the primer.
