Hi, I want to use plastic lids to make little trays or coasters decorated with paper art. I plan to leave the finished item in the lid. I assume I will need to pour a thin layer of resin and let it cure, before placing my art and pouring another layer of resin. Yes? Will Mod Podge work to seal the paper art? Will Envirotex Lite Pour-On work for this project? All tips are welcome. Thank you.
