The reason I am saying to use fiberglass cloth and resin is to protect the foam core. If not it will be structurally weak and more likely to break. A lot of people use epoxy as a glue and most hardware stores sell it that way, but if you go through a diy surfboard repair and home build they sell epoxy to use with surfboard lamination. Look at greenlight surf supply or more like it.
Polyester resin is much more accessible and can be found at hardware, marine, and automotive stores in kits of bondo. You can also get the resin and cloth from a surfboard home build store. Polyester or epoxy will work on a wakeboard since the foam they use is polyurethane and not polystyrene.
About cure time, you can use it after application in less than a day, but if it is still sticky the fresh coat will “blush” meaning that nice clear coat will turn white because it hasn’t finished the reaction and will react with the water.
I’m not sure if I’m seeing the picture right, but there looks like there might be some core damage. Make sure you use some type of filler. If either resin pools into something, it will get so hot that it will start melting anything it surrounds. Look up YouTube videos on ding repair on a surfboard.
