Match drilled, deburred, edge-finished and dimpled the F-851-L/R and F-850 fwd bottom skins. Also countersunk the fwd and aft crossmembers. Once all that was done, I cleaned and primered all the parts, including the gear leg mount brackets, and touched up the scuffs on the Grove gear legs as well. With all that done, I now need to order some firewall sealant and some proseal which I will need when it comes to rivetting these parts together. I feel an expensive FedEx coming on :-(
