Managed to get Sunday afternoon in the shed and finished laying up the inside of the bottom part of the fairing. It takes 'time consuming' to a completely different level when doing this, but the result when finished is great.
Just wiped it over with acetone, then coated it with resin and some 30 gram tissue. Not much finesse needed to do it, but once fully cured, I'll block it back with 180 grit paper and then 320 it smooth. There's no air bubbles in this coating, so it sands back lovely. It's just a slow job.
Its hardly put any additional weight on the upper fairing section I did a little while ago and the difference is amazing. Won't ever do it again, but glad I did it this time. Aiming for primer this coming weekend.
