Since it takes a full day to cure I started the day by rolling a layer of clear epoxy resin mix on the FAB to fill the surface some. Once done with that I started to ready the left aft baffle for riveting. I first had to drill the holes for the AN3 bolts that hold the oil cooler in place and the nut plate holes. Once I did this I clecoed it all together and confirmed the fit, once happy with this I took it off to begin riveting. I had to dimple the holes first but I ran out of time before I finished the dimples
