an Idea!
get a plain smooth one, take it to a bed liner place. the texture of the bed liner is based on the amount of grit they put into the lines... some liners are glossy some dull, some rubber like some sandpaper line...
check out the back of a few trucks get the name of the people that do the finish you like, and see if they will put just the right amout of grit in...
tell them you are trying to build an old mussle car, they might shoot it for free, or little of nothing (especialy if they are getting ready to do a bed.
of you can go to the auto parts and get your own kit and spray it yourself. ....
might work out to be a fair comp...
course I been told I was smokin krak once already this morn.
