I've used "Rhino Lining"
Protective Coatings, Epoxy Flooring, Seamless Flooring | Rhino Linings
Not cheap...a bit of rooting about...but looks good and works well.
Superformance ( and others) have also used what is basically "Wet suit rubber" glued under the guard.
I recon that would work well also.
Cheers,
Warren
