If you want to DIY it you can buy a kit called Bed armour by duplicolor.
It has Kevlar in it
Autobarn, supercrap they should all have it.
I used it on my ute, all I can say is do two to three coats. I only did one
as I ran out of time.
But for only a couple of hundred dollars compared to $$$$ definitely worth while
