Reality check.
These are wheel arch liners, a.k.a. splash guards. Super soft and flexible plastic that will take the pounding of stones thrown up by the tyres and prevent most of the water splashed up under the guards from going further. Zero structural value and often have to be bent almost in half to fit. Some of the European car manufacturers use a thicker, harder plastic, but it's essentially the same.
The plastic has an oily feel to it when new - so probably full of mould oil and likely it is recycled, or mostly recycled, plastic and of rubbish quality, despite actually being suitable for the job.
IMHO adhesion promoter and epoxy, then paint will be an abject failure, even if you can get it to stick. The pounding from stones and other road debris will destroy the paint in no time.
Of course, if the car is a trailer queen, then go ahead and paint them, but if the car is being entered in competitions then the fact that they're painted, i.e. not original, will see loss of points.
As I said before, judicious use of heat, preferably using a heat gun, may very well work to soften the scratches, making them less visible. Practice first on an old one to understand how much heat that plastic will take before it turns, instantly, into a black puddle.
