Metal spars according to the ad. My brother's Cub was covered in 1968-69 and the fabric is still good. It is a metal spar wing and we inspect it internally with a camera from time to time. He currently has the plan down for repair of a bent longeron (my fault....hit a hole while taxing), some clean-up of patches, wet sanding, new boot cowling, engine cowling and new overall paint. The 1969 fabric (Razorback Fiberglass) will be retained. We tested the ribstitch cord and it held up just fine. The plane will look like new when completed, but will still have 40 year old fabric. Of course, it has always been hangared too.Man, I don't know. Covered 28 years ago? There could be 4 cracked ribs and ant condos in the spars and you'd never know it until your wings started fluttering in the breeze. I think I'd pass.
Cotton and Irish linen don't fall into the same category as Ceconite or Poly-Fiber (aka Stits) as they aren't a natural fiber or material. I would argue polyester fabrics are more akin to Razorback than cotton.Please correct me if I am wrong (happens occasionally ;D ) but isn't Razorback covering fiberglass cloth? If so, I don't think Razorback covering falls into quite the same catagory as "fabric" meaning cotton/ceconite/polyfiber etc i.e. the glass fiber will be impervious to deterioration.
