The link takes me to Evercoat 'Medium Set' epoxy, it claims to be "Designed for replacing door skins, roofs, quarter panels, truck bedsides, utility vehicle sides and other non-structural panels".
It's the 3rd bullet point after the name.
It does mention 'good gunability in hot or cold conditions' which I take to mean that it will come out the end of the tube fine over a wide temperature range (as opposed to freezing up below 68* or being too runny above 75*).
But no mention of oil, fuel, or any other type of powertrain fluid resistance (they usually brag on that if it is).
