James,



I use McMaster clear polyester film .010" (part number 8567K92)



Unfortunately they only sell it in 10 foot lengths (by 40"). So unless
you need the lifetime supply, I will be happy to send you some gratis
off of my roll. Just let me know an address.



BTW, here is the link to the flap wiper template(s) that I use.

Regards,



Larry

Does anyone have a source for mylar that can be used to construct
flap-to-fuselage gap seals for an LS-3a? Also, does anyone know the
proper thickness of mylar to get?
