more resin after waxed coat?

hi everyone,i have made a mistake on an overlay set and need some advice…
I use polyester surfboard resin so for the final layer of resin i use 2% wax additive so it will fully harden,question is can i now add an additional layer of resin over this waxed layer??
thanks

The wax additive goes to the surface of the resin, this cuts off the oxygen and allows the resin to fully cure. If you sand the surface well, and clean with acetone, you should have no problems. Its just an overlay, so you need to worry too much anyway
