Recently purchased an Ercoupe 415-C. The wing covering is now @ 30 years old, discolored white (insignia white?). The fabric seems very good even after all this time as the plane was hangered and unattended for many years. Wishing to deep clean the wings and/or to repaint the wings without removing the fabric. Happy to receive any advice as i am a novice owner after renting up to this time. My coupe was recently annualed and all seems structually good.
Thanks,
Al
