Per Vendor: "On the metal airframe, prior to attaching the fabric, the glue needs to be mixed 2:1 2 parts glue to 1 part acetone. Apply two coats of this glue to the frame and let it dry completely. Then position the fabric and use a mixture of 1:2 (1 part glue to 2 parts acetone) to reactivate the glue on the frame and get the fabric to stick. This same 1:2 mixture should be used for attaching the tapes as well."
