Like I said in my very first post, I did NOT build the airplane although I have rebuilt or replaced just about everything in it at this point in time. One thing that is still the same as when I bought it is the headliner. It is some kind of very course material that he obviously used a contact cement on. It has held up well and as you say looks good except under the front windshield. I will be taking my airplane into annual next Monday and plan to address that issue for the first time in about seven years, everything else has been replaced or updated. New paint, new panel!
