I hated it. Worked on it for weeks fixing pinholes, too-dry honeycomb, generally poor fit, etc. Eventually I hired an airplane paint shop to help me with it and they said they'd only work on it time & materials as their experience with Vans FG has been horrendous.
It's FG, so you can make anything look good with enough time, and this is my first experience with FG so I don't have much to compare to but what I've heard.
I hear good things about Sam James and if I build another RV I will buy his cowl.
