The instructions suggest drilling/dimpling the top flange of the rear spar in the area of the re-inforcement plates only. If I follow these instructions and then prime the spar and plates, I will mess up the primer coating when I finally come around to drilling/dimpling the rest of the flange holes. Is there any reason why I shouldn't drill/dimple all the spar flange holes right now before I prime the spar ?

When you cleco everything together with the skins, the will will self aline (with a little help from you). The directions are to do this with a plumb bob before you rivet, but it was suggested to me to do this, check wash out/wash in, before match drilling.

I tend to get everything ready to rivet before priming. As for drilling out the holes after priming, no big deal. The rivet will fill the hole when squeezed/driven and there will be very little chance for moisture to get in there. Since I hope to put my RV-9 on floats some day, I keep wondering if I shouldn't spray the rivet heads as the parts go together. Sanity prevailed and I haven't started down that slippery slop. If you don't live on a island in the middle of the ocean, all this corrosion protection is probably overkill. Just my $.02 worth. Bill R.
