I set the F-772 floor skin in place, then pried the F-770 side skins out with popsicle stick and applied 3M Fire Barrier 2000 to the firewall flanges. A little judicious bumping with the heel of my hand got the F-772 into it's final position, then I squeezed the rivets along the lower flange. The sides are clecoed together with a cleco in every hole and will likely stay that way until the finish kit shows up and I can see what I want to do about cowl attachments. I would have liked to go ahead and squeeze those rivets too, but others on VAF have assured me that as long as I have a cleco in every hole, there is enough squeeze out of the 3M product that I won't have a problem just leaving them clecoed for now. I'm leaning toward using piano hinge up the sides of the lower cowl per print and then going with cam locks for the cowl seam and where the upper attaches to the firewall, but that' s a future decision.

Robert came over after work today and we shot/bucked rivets for about 4 hours. Got the sides done pretty much all the way back to the F-705, not including the floor stiffeners up front. One or two more sessions and this thing will hopefully be ready to flip!
