Jim... just a butt inski here...but WHY?
Maybe I am not paying close enough attention
BUT--- I thought the exercise was to do a Fast and very Strong covering method--- USING poly/tissue/silk and then--- one of the super lite plastic coverings Like SLC, or thin FasCal/ mica film
IMO MonoKote--- or similar--- has already all the strength and color needed by it self
That said...I think the initial covering (tissue/poly span/silkspan/silk) is put on traditionally nice and tight on the perimeter and only ever needs stuck down to the ribs on a polywog rid set like a Ringmaster....all other rib types should be left free so the SLC/////ect,...can shrink and stick to the first covering without adding torque to the ribs or balsa wing
I use a lot of Poly span and silk on wings.
I think Larry Renger found a way for US to NOT have to add weight with Dope and Use the Lite coverings (SLC/Doculam/FadCal) as the shiny top cote and the added benefit ...by accident...was that the composite of the two coverings saved time, looked good...and structurally was tougher than traditional method using dope to fill the paper/tissue/cloth
Bottom line is...IMO MonoKote covering does all this by itself.... But that said--- no MonoKote can look or be as strong as a traditional silk n dope method or Larry Rengers discovery method
EDITED in after sending...Jim I DO NOT intend this to sound as harsh or judgement as it does....
Just curious how you arrived at following this method to think about using MonoKote over something else.... mostly because early on, I GOT the notion Larry was trying to show four things...Light weight, faster, looks good, stronger (an accidental by product IMO)
And BTW
NOT TO take away from Larry-- But I think Bobby Mears, INDEPENDENTLY--- found a very similar method so he could rapidly finish dozens of Nostalgia combat planes for the Combat Museum...IIRK He experimentee with fogging the back side of SLC/FasCal/Doculam with paints to simulate the Silk n Dope finish and found it was just as easy to do a polyspan heat shrunk and then the plastic and looked just like a silk n dope finish
