I’ve never used wood glue to paper fins - believe it or not my go to glue for papering is Elmer’s School Glue. Lay down a bead, spread with on old credit card, lay on the paper, use a clean card to smooth out the paper, layer between a couple of dollar store plastic cutting boards then weight with as big a stack of books as you can. Let things rest that way for a day or two until dry, trim/sand the edges clean, touch up any loose edge spots as needed. Sealing with thin CA is a good option but sometimes I forget until after I already primed so that doesn’t always happen. I’ve been papering my fins almost since I started my time as a BAR - going on ten years now...geez I’m old
