STK, I really recommend West systems epoxy -- the longer cureing time, allows the epoxy to soak into the wood --There is also a thickning agent they recommend for filling all voids !!( available from marine supplys)
I don,t recommend polyesters at all, as they cure to quickly, and don,t penetrate ( been there, done that -- won,t again!!)
I also use west systems to coat the entire blade assy, before painting and use acrylic enamel, for top coat ..Have also used , several coats of west system and sanded with 220 paper, between coats -- then polished it to a glass like finish -- it has UV protection and it,s really pretty on mahogany props !!
Incidentally -- mahogany works real good, and I have found it cheeper than vertical grain fur !!
I don,t believe you can use, to good a glue -- it,s to much work, not to and laminated props are stiffer, resist bending !!
Good luck on your project -- we,ll look foreward to pictures !! Bill H....
