advice on ding repair

Hi guys,
Now this might be an insanely dumb question but I'm about to do my first ding repair and don't want to screw it up. Basically a small chunk near the tail came off and I got some Suncure resin from the surfshop to fix it. Now it says on all the instructions I could find to apply it in the shade and then expose to the sun to dry - problem is, it's been raining here for days and probably won't stop for another week or so with no end in sight (surf is still great tho). So the question - can I just let it dry inside and will the effect be the same or does it really have to be exposed to sunlight? Anyone got experience with this?
Thanks!
