RE: Fiberglassing F20?
It can definitely be done with only a small weight penalty- I like to use .75oz. glass, Z-Poxy resin mixed with rubbing alcohol which will thin it a bit more, and give you a real long working time---Make sure you squeegee the excess resin off the surface after it has been applied- that is where the weight comes from... A Credit card works well-
Also, some folks use fast Zap to tack on the glass then work the large portions with the resin-
Check out the threads on the CBM F-16N, some real good glass tips and tutorials there--- I have only done the F-16N (Foam) and some smaller pieces on regular airplanes... I am far from expert but I would love to have a Patriot that is glassed so I don't have to worry about the freakin' covering all the time--
Keep us posted!
