I recently purchased a light aircraft (maximum gross 550 lbs) the was covered with PolyFiber Light (1.7 oz./sq. Ft.) many years ago. The fabric seems good to me but I’d like to test it. I don't have access to a Maule tester and new ones are over $500. I’ve seen the reasonably priced Quicksilver tester but it is calibrated differently and appears to be intended for testing dacron. I’m wondering it the quicksilver tester would work? Thanks!
