Outside and inside corners were more challenging than the flat surface. One needed to be careful to shape the filler. On inside corners it was more of a challenge to sand the filler.
I must have enlarged my bicep by four inches after the sanding season was over. There was much work and effort performed here, and I have heard that preparation before spraying is 90 percent of the work. This effort felt like 190 percent of the work. Still I would sit in the cockpit on a nice sunset evening enjoying the moment, and occasionally notice the ugly looking cockpit; at such time I decided it is time to at least improve my recreational surroundings, and besides, it will increase my skills at body work and gel coat work.
