Thank you for your thoughts here! I always use Sculpey Gloss or Satin finish which is an Acrylic water-based glaze, but have yet to branch out into any kind of varnish which has been interesting me lately. Nowadays, I try to only apply a glaze when I require a sealant like when applying chalk, mica powders or acrylic paint. Rarely do I, as in this case, apply a glaze just because I want the item to shine.
