The heat sucks in the summer, I covered mine with new carpet and padding to reduce the heat coming from the trans. tunnel.

I really like not having carpet to worry about, but I will second the complaints on heat from the floor. Also, I suspect it is louder in the cab with no carpet, though I don't have a frame of reference for comparison.
I did the U-pol stuff
Pros: lots of auto paint shops are starting to carry it around here at least, very easy to spray, has held up great i have abused the heck out of mine firewood metal toolboxes dragged in and out of the back. No problems. its cost effective.
Cons: Hot inside when in traffic on a summer day. Added a fair amount of road noise to my rig not a crazy amount.
Raptor here. Love it.....no fading, cleans out easy, goes on nice. It could be a bit tougher but I just touch it up whenever it gets dinged. My transmission must run cooler than most because I can touch any area after being on the highway for an hour with no problem.
I put Monsterliner in mine this spring and I like it. I can't really tell a lot of difference in the noise or heat but I still have a piece of carpet in the back for my dog to lie on. One of the best things I've done to my Jeep.
I used Hurculiner that can be rolled on, but I borrowed an under coat gun and sprayed it on. The finished job after two coats was perfect everyone that has seen it loves it. I don't know how well it looks rolled on... The cost was $85 bucks for a gallon at Advanced Auto. You will need some painters tape, paper or plastic to cover what you don't want covered, and some Acetone or Xylene. All said and done I think I spent two days (one full day of prep.) and about $100 dollars. It was well worth it. I got caught with the top off Sunday in the rain. I just pulled the drain plugs and I was off! No wet smelly carpets! Good luck, prep is everything, take your time and do it right!
Nice, $100 is what I expected for a DIY, undercoat gun huh, have to look into that. Whats involved with prep? Mask off and a good wash? PS: Just check Ebay, they have an undercoat gun for $20... Thanks
