im ordering those ice cube trays used to make the colored buttons on the Original star trek. i was wondering what do i need to appily anything in the trays to prevent the resin from sticking??
im making resin lightsabers which have a metal tube inside to insert the blade and reinforce the resin
my question is this
how should i insert the tube? Should i insert it while the resin is drying or should i secure the tube in the center of the mold and then pour the resin in?
