This post just came in on the main CC thread.
The Varathane he used... water based polyurethane (wbpu) is similar to a water based finishing resin by Deluxe Materials called EZE Kote that I just used a couple of days ago, along with 24g cloth, to glass my Super Cub's wing tips. Very light weight especially if you don't use the cloth... which I wouldn't on something as small and CG sensitive as the CC.
Some guys like the Minwax Polycrylic which is an acrylic (the "poly" stands for polymer... it's not
polyurethane) hardened wood finisher like the wbpu.
