As with most builders, I didn't get too many pictures of proseal in action. Before I got to the fun stuff there were are couple of tooling holes in the end ribs that needed to be filled with #6 rivets. The plans suggested mounting the rivet gun in the C-Frame to buck these. I used that method for the first few, but I overlooked the other end ribs and installed them without first filling the holes. I bucked these using my 5lb back rivet bar with no problems.
After seemingly endless prep work on the skins and stiffeners I finally had my first proseal session. It was messy and nasty, but I knew that going in. Many people apply the proseal and 100% cleco and wait for the proseal to cure before riveting. Again, I decided to stick with Van's and rivet them wet. It was not not fun, but mission accomplished.
