I shot primer on the Ailerons and Flaps today. It took a few days to get them all scuffed up, cleaned and ready for primer. Of course, the prep is always where the work is, only took an hour or two to spray them and set them aside to cure. With a quick scuff and wipe down, they'll be ready to cover.
I shot them with NASON 2k Acid Etch Primer.
