my bro and a friend of ours did one that was ppg spray on, tintable bed liner. it turned out awesome, it had a lot of texture and was on pretty heavily with only 2 coats. he could have kept sprayin to make it thicker, which is acceptable, pending on how thick you want it. he had to buy the gun to spray it but it was only like $50 from the paint store. we just had to scuff the bed and mask off what you dont want sprayed and lay it down.
it looked pretty easy, i didnt really feel like you would need any paint experience to do it. it lays on kind of slow, just cover it lightly, use your judgement. he said you can get them from ebay with the gun for cheaper than you can get from the paint store, also black and tintable were available, for about $275. we plan on using it again for sure
