I have the herculiner in my 87 Wrangler. It is a thin rubber type material, alot like rhino truck bed liner. It is really nice if you just want to hose out the inside of your jeep to wash it out. I noticed that the floor gets hotter because it is black and it is also noisier. I'm going to put carpet back in mine because I don't like the heat and noise. I don't ever get enough dirt inside to really make it worth while to just take the hose to it. Most carpets clean up rather easy by getting them wet and then using a vaccum. Depending on your use of your vehicle you might like it better than me.

I don't know about Herculiner, but I have my entire YJ Rhinolined, from the tailgate all the way up under the dash. I put it down as my best mod so far, it makes it so easy to clean (I haul a lot of sh*t around, and like to play in the mud).
I agree with JeepTodd stay away from black, (mine is grey), now there is a multitude of colors out there.
The only downside is it was not cheap to have installed.
There is sale at Autozone, $99 for the kit and a gallon of Herc. I have been told this is more then enough to do a Jeep with couple of layers. I have heard Herc is some good stuff. Just buy it and read the instructions.

We did the inside of a YJ with one gallon from Kmart for $99. That was enough for two coats with a little bit left over.

I did the entire interior of my XJ with less than one gallon. It transfered the heat from my auto tranny a lot more than the carpet and it was much louder. It will keep the floor from rusting and a little easier to clean and harder to ruin.
