What should I use to bog the peel lines?

So, it FINALLY arrived!

I’m looking for something that I can rub in to fill the deeper bits, before I sand- what would you guys recommend as far as sandable fillers that will stick to the resin, and stay stuck while taking moulds and/or painting?

aaanyone? anyone at all?

yes, smear some of the resin using a small brush. Then cure with UV light. Then sand.
