Hang both ailerons after sanding the residue of hangar neighbors errant foam spraying job.
I made out good compared to neighbor and friend Jim's new Cirrus... half right wing covered with this shit.....doesn't come off even after a call to Cirrus for recommendations. Jim gave me hangar tenants number... I will call tomorrow. Alerted Dan Reeves in hangar 7 next to me...his RV-7A under construction likely got sprayed too.
I sanded stuff off off the ailerons I wanted to hang today. Should get another coat of WLS now.
