Ding repair

Tonight I want to repair a small ding in the tail of my board with a ding repair kit. It says to put in sunlight to gel resin but it’s not sunny and I don’t have any special lights. I want to use it tomorrow morning, what are my options?

Thanks

Basil,

It doesn’t have to be sunny for the sun cure resin to harden. It works on cloudy days,too. Of course, if it’s night out your out of luck unless you have a uv bulb.
