Certified food-grade PETG + food safe resin seal is the best from what I have read (I researched a bunch as I am building a greenhouse)

[–] Marafon@sh.itjust.works 8 points 3 weeks ago (6 children)

Thank you for the knowledge! It looks like foodgrade petg is 3 times the price and I don't plan on changing nozzles and stuff to keep everything kosher anyway. So I reckon I'll use regular petg and hit it with Shellac for the redux. Unless you have a food safe resin seal to recommend based off your research?

Thanks again!

Hobby woodworker here. Shellac is great for an initial seal, but isn't waterproof. I suggest using a two part epoxy instead. You don't need a very thick coat, so you could even use a crack filler and/or self leveling variety.

Many 2k epoxies aren't food safe, hence the recommendation of food-safe resin as a sealer.
