heh, I also just recently picked up a JKU to go with my TJ. The TJ gets more waves than the JK, but I understand that JKs don't always wave, so some people aren't used to getting waves from them.
I've stripped most of the plastic off the JK in preparation for the MetalCloak fenders, body armor, and bumpers that I am prepping. I had a few of the pieces powder coated the wrong color, gah, taking them back for the 'right' color tomorrow.
The TJ already has MC fendors, body armor and rocker rails.
