Rich, Thank you for the kind words. As far as the bed-liner paint goes, I generally use USC Dominator. It's super easy to mix and spray. As to why I prefer bed-liner paint to traditional undercoat, I like the way you can achieve the look you want plus have the added benefit of mush easier cleaning once you start putting miles on the car. Also, if you want the painted undercarriage look but still want to actually drive and enjoy the car without worrying about the undercarriage chipping, this is a great way to have your cake and eat it too. Think trailer queen without the need to trailer it. The other benefit is should it actually chip, you can just dab a little paint on the chip and it is invisible. Plus, instead of it being a two step process of spraying the paint and undercoat, you get it all done at once. Believe it or not, I have even used it on a few of my boat decks with a little non-skid additive to liven up the deck and still have it be worrying free (does not chip when you accidentally drop lead on it). Fish blood and guts is easily hosed off even after it dries. AND it costs way less than traditional boat gelcoat.
