Brain came back to life. I did it wet.
I put a row of rivets in, held in with back rivet tape, then applied a very thin layer of Proseal to the Stiffener only. I wiped off the excess Proseal from the rivet shank before I set them just to make it a bit cleaner. Results where very good.
Here is a link to Randy Lervold's RV3B build. One of the best resources out there, and still on the web. Thank you brother Randy.
