Add F and PE Resin for Wax?

I have no idea what I'm doing with PE resin.  I'm an epoxy guy.

I am doing some minor ding repairs for a friend.   I have some laminating resin from the local fiberglass and chemical supply house.  Can I use Additive F as the wax component so I can sand the fill/finish coat?  Is there some readily available alternative?  It's an 1.5 hour trip to the nearest supply house, and not sure they will even have what I need.

All the best
