Gary you completely misconstrued both of my posts without really reading them, the question was by the OP in this trainer forum thread is it OK to cover only the parimeter of his wing without out sealing the ribs.

The implication was being made by responders that it did not really matter. Well My response could only be it is dangerous to cover a trainer wing (remember this is after all the trainer forum) 'Without' sealing the ribs and I will stand by that agine and agine.

Gary take a Senior Kadet wing that is kit built and has only been parimeter sealed compare it directly with the exact same wing that has been covered and all surfaces sealed then the unsealed rib version and the lack of stiffness will be shocking and yes I have done exactly this many times as well as seen this result many times expecially by the fellows who refuse to seal the ribs.

Like I Have said I am not any kind of an expert nor have I ever been but what I am is a survivor. So I will not argue about basic cellular structures but willing Jack Northrup would have back in the thirtys with his Alpha and Gamma monoplane wings which became the basis for his multispar cellular wings for the DC-1,2 and 3 wings as well as just about everything since.
