I did another round of sanding with 400 grit. Then cleaned the cabin cover. Everything looked great. Then Brad assisted me in applying Loehle Wonder-Fil. I then shot a coat of primer. Every missed blemish stuck out like a sore thumb. It appears that I'll be spending the next couple sessions fixing all the blemishes that the primer high lighted.
Have I said how much I really like fiberglass? Not!
