I just got my toolbox back from the local truck shop where I had them spray permatech on the inside of it. I was fed up with the aluminum "chalk" over EVERYTHING! so this is my way of solving that problem. So far I'm impressed, I looked into the do it yourself stuff but I would have had the same cost but I would have had time into taping everything off, mixing the crap etc... I also had to add the "Cummin not strokin" decal since it was collecting dust with nowhere to put it. (more pics in my gallery "Ians mics pics")
