well...I watched the RV 14 vid on the vansaircraft site, and had all intentions of doing it like them, but....I did a test of epoxy and glass fabric on plexi and aluminum....after curing they cam right off with one finger, WITH severe surface prep! and I am not that skilled, so I just plied on 10 or 12 layers of fabric saturated with west epoxy, stating with narrow and then fat ones, and added two layers on carbon on top. popped it off the packing tape the next day and started sanding with a 12" block. about 3 weeks. couple hrs a night and weekends. then Sikaflex onto plane. windshield was Sika on prior.
