http://www.rockcrawler.com/techreports/herculiner_bronco/index.htm I've used Herculiner in a '85 chevy s-10 bed - good results. I didn't buy the coating so it faded in the sun - but they sell a coating that is 'sposed to help keep it shiny.
I believe the durabak also comes in different colors.

dupli color also has a diy bedliner but I have read unhappy things about that product... doesnt' last, peels, chips...etc..
