Petrol Resistant!

[robin.springer]

Hey guys


was wondering if anyone has found a petrol resistant filament?

I just posted this in chat, but with your Hyrel you can print with PEEK, which is dimensionally stable as well as chemically resistant:

no data against Petroleum though :-(

My Google-Fu is weak.
