OK... seriously. I do like Pearlie, except I don't put down a sizing layer of glue. I use TB3, soak the rawhide in luke warm water 'til it's pliable (half hour) , rough sand the bow's back, coat both with glue, lay it down, smooth it out from grip to tip, "petting" vigorously.
I use wax paper over this after it sets for a bit, and then lay a strip of leather over that and GENTLY wrap the whole mess with innertubes or an ace bandage. Leave overnight, unwrap, trim edges, sand sides... good to go. In my book, for rawhide, thinner is better.
