Scratches/Gouges in composite bed liner - how to touch up?

I know it's just a bed and they are made to get scratched etc.

However, I just got my truck two weeks ago and already put a few gouges in the bed from hauling things last weekend.

My question is, what is most likely to match the composite bed the most? Rust-oleum truck bed coating, plasti dip, or just a regular outdoor black flat or satin spray paint?

Any feedback is appreciate. Any negative responses regarding babying the bed of a truck can introduce their fingers to a blender, lol.

 

Bed mat. Best 100 bucks I ever spent

Lol, put more scratches in there and those 2 won't bother you so much

 

Agreed on bed mat!!
If you do want to fill them, try PTEX maybe? We use it to fill gouges on bottom of snowboards. It comes in black. No idea if it would work, just a thought.

 

Sorry should have specified, I have the bed mat, it's the sides that I'm referring to.

 

Thanks for the suggestion, I'll have to read more on the ptex as I'm not familiar with it!
