Hello. New to the forum and new airstream owner. We recently purchased a 1969 27í Overlander. We intend to use it in a set location not for traveling the country. Iíve tried and tried to search the forum for any information I can get on interior skins, but the more I read the more confused I get. So, what are the interior skins made of, aluminum or fiberglass type material? Ours seems to be some type of fiberglass, but I canít verify that. So, whatís the real answer? How do I patch holes that have been cut in the interior or holes from items that are no longer there. Iím sure thereís an answers on here somewhere, but I just canít find them. Iím sure Iíll have 50,000 more questions before this ordeal is over. Any help would be greatly appreciated.
