You can if youkknow a surf shop pick up a little pigment, but I wouldn't bother as so little is needed for a ding like that, you need a small glass patch and when your are done there will be only a little scar on the side of the board. if it is any where near where your legs hang then ensure your finish is smooth so you don't abrade yourself. get the ding all or a full ding kit, solarrez is an emergency kit. It's fun to do your own repairs heaps cheaper and you get better as you go, more surfing = more dings = more repairs= the better you get a fixing.
Major tip don't do it inside your house read instructions for clean up and safety, but have fun, do not be tempted to add extra hardener ( catalyst) fire hazard. mix hardener and resin really well and if in doubt do it little by little! It's how we all learnt

I've taken up troll hunting just for fun, instead of a rifle I'll just use a pun!
