Nothing in the supplied comments is a chemical test. The rows below are those materials' print settings. They are not a resistance chart.

What the comments actually say

a Reddit thread in r/3Dprinting: "Depends on the thickness of the fiberglass. Better to use it to make a mould and use that for fiberglass. That way you don't have melting stuff inside."

a Reddit thread in r/3Dprinting: "There is a guy on YouTube (lasersterling) that built an entire Lamborghini replica body with this method. Seem like he didn’t have many issues but time will tell."

a Reddit thread in r/FixMyPrint: "Try two-part epoxy. Cyanoacrylate glue does that."

The rows the summary names

SUNLU PP lists a nozzle of 210–230 °C (410–446 °F) on the product page checked 20 October 2026. The bed cell is empty. PP is the material hub. SUNLU is the brand index.

PrimaSelect PETG lists 225–245 °C (437–473 °F) and a bed of 70–80 °C (158–176 °F) on the product page checked 20 October 2026. How to print PETG is good PETG prints. PETG is the hub. PLA versus PETG is the functional-part split, which is not a chemical ranking.

What this is not

A printed part that touches food is food contact. Prusa's article there is about the printed object, not about gasoline.

Pros and cons

Questions

Do these comments say PP, PETG, or nylon resists oil or gasoline?

No. The supplied comments are a stew joke, a fiberglass mould suggestion, a Lamborghini-body aside, and a switch from cyanoacrylate to two-part epoxy.

Where is the MEK question?

The food-contact page is the neighboring limit this catalog does document.
