just wondering if any of you LCO's or others that rome this sight have put in a spray in bed liner in their enclosed trailers, i just got mine the other day and would like to put it in to help rotting from fuel spills, water, etc.. (using a roller though and not spray cans.) so its a 7x14 box trailer with an 18" vee nose on it. and i would like to keep this under 200$ so i was planning on getting herculiner from autozone... am i in over my head or is this do-able? any tips... Thanks, -A.J.
