I am with the truck box liner idea.If it was a show car or gunna be a really nice ride .I would go as far as to have a bed liner company spray the good thick stuff on em.I am sure the roll on or sray on stuff would be fine for a every day driver.But the a bed liner company spray on would be the best .When the pros spray this stuff its almost a 1/4 inch thick and if I saw some ocassional burnouts in the future it would sure be nice not to worry with a thin coating!!
