Its impossible to convey just how much work getting the carbon fiber on the sides ready for paint was. When you apply fabrics there is a weave texture that needs to be filled in. Not a big deal for the fiberglass on top thats getting painted since we can just fill the weave with fairing compound, sand it flat, and go. The carbon however we are leaving exposed. I fill the weave by applying several coats of epoxy. I had to do 5 which is a little more than typical. Between each coat I sand it back close to the fabric using about 220 grit, being very careful not to remove the actual carbon. The sanding back is to avoid having a thick layer of epoxy which can crack, but also makes a milky or yellow layer in front of the carbon we want to minimize. After about 6 straight days of epoxying, sanding, and letting my arms recover, we are left with a uniform gray surface. At this point i give it one last epoxy coat and to make sure there are no carbon fibers exposed - if you hit any carbon with sandpaper at this point the clearcoat wont stick to it. This final epoxy layer gets sanded up to 400 or 600 grit. The second picture is masking for paint.
