Frustrating day today because of the plans. This is what the first step on page 29-03 says: "Mask off the forward and aft mating surfaces of the U-01402 Lower Gear Braces and prime. First, the plans VERY rarely suggest priming so even though I'm priming everything inside anyway, I pay attention when they mention priming. In this case, the diagram shows the parts in question oriented as they are installed (fore and aft). The front side attaches to a spar and the rear attaches to a bracket. After priming you bolt these parts in. I consider these two surfaces where the parts get bolted in the fore and aft mating surfaces. I think 95% of the public would as well. Nope! I checked the Wiki just to make sure (as I always do) and it had a comment calling into question what the fore and aft mating surfaces are that you don't prime. I ended up contacting Vans and sure enough, I skipped priming two surfaces that should have been primed and primed three surfaces that shouldn't have been. The picture attached here that shows the yellow surfaces are what you DON'T prime. They call those fore and aft! And BTW, nothing gets "mated" to those surfaces for dozens of pages. Anyway, all I got done today was removing the primer that shouldn't have been sprayed on and priming the sides that Vans says should be primed (which are the fore and aft sides that are mated to the fuselage!). While I was at it, I also primed a small section of one of the bottom fuselage skins where it overlaps the other bottom section. This is specifically called out in the plans. Basically I ended up priming both sides of part of the bottom skin. Oh, I almost forgot. I also removed the factory bracket that holds a 12v socket located between the seats and replaced it with the bracket that Classic Aero includes with their interior kit.
