PETG Colors

ABS
ASA (Easiest to print that survives in 165F degree car. )
Nylon
PETG Some Distortion at 165F car.
You don't need to rule out PETG entirely. If you know for sure a part won't be exposed to more than 60°C, 140 ( It can get up to around 125-135*F under the hood. I have CAI and at a stand still with the engine warmed up, my IAT is around 120*F. This is ...)
then PETG may be preferable over ABS if the extra flexibility is
desirable, or if the part will be exposed to chemicals that would affect
ABS but not PETG. I have printed PETG parts that are extremely tough
and don't deform when heated to 55°C for extended periods. The key is to
print it hot enough such that layer adhesion is maximal. I had to
slightly exceed extrusion temperatures recommended by the manufacturer
to get the best results. If the surface of the print isn't perfectly
glossy, you're not printing hot enough.
