I used epoxy to glue the fairings on. I cleaned the gear, a slight rough sand, and put them on. The fairing, gear to fuselage, was done in blue Styrofoam, in two pieces, glued together then glassed with two lightweight and two medium cloths. I then removed the foam with a soldering iron, fitted the fairing and CA'd it to the gear fairing. Now I just need to sand and paint.
