Is it necessary to seal or varnish a project created using Apple Barrel Pouring Medium?

Projects created using Apple Barrel Pouring Medium mixed with Apple Barrel Acrylic Paints MUST be sealed.  Project surfaces can be spray sealed using Apple Barrel Acrylic Lacquers (Matte, Satin, or Gloss Finishes) or brushed with Apple Barrel Artists’ Varnish (Satin or Gloss).  NOTE:  Before storing finished marbled projects, surfaces should be sealed to keep projects from sticking to one another.
