The bow I just done is a hard birdseye. on some maples it will completly saturate it. There will be dense places that does not take resin. Some will take on enough resin that it dont float. here are a couple of pics of different maples. The first one floated after 4 days soaking
. The second did not float and is pretty much colored all the thru. I dont think the hard rock maple(the white stuff would take much at all. Soft maple will and be better with resin for a riser but would need reinforcement. Dean I use cactus juice with alumalite dye. And smooth on with no problems.
