I have always stayed quiet on this forum, so nice to meet everyone ^_^
but honestly from a value standpoint, i think this looks terrible, so terrible i had to find my login and post
However, how about, since we all love a cheap fix, (and yes im 100% serious because i believe this MUST be an improvement on your work) why dont you find some heavy tread cool lookin old truck tires that are just rotting in a pit in the woods somewhere, chop the tread off real nice and try to fasten that on top to hide these atrocities.
I think that might be really cool (at least in comparison,) certainly unique, and super cheap
Im not trying to bash you and i did my best to offer a unique solution here, but please listen to your fellow jeepers, change this somehow. Hmm, in keeping with the budget of almost zero (-$7), maybe you can wrap the tread around a reinforced yard hose holder or cut up steel barrel or something...
Or perhaps you can find an old clawfoot or lions head chair for free on craigslist in an arch sort of shape and rip the arms off that, itd give a whole new meaning to "Pirate 4x4" :P
Maybe this would be more to your liking, resources available to anyone and everyone! I haven't researched the subject much, but try this link: http://www.youtube.com/watch?v=cOa1kHEiIpg
(start video at 4 minutes to skip talk) thats right, cardboard. Surely you can cut a fender design, preferably out of many layers and laminate them all together and spraypaint black over it. Hell I heard a story of somebody bein ripped off buying a muscle car because the trunk lining was made of cardboard, covered with bondo smoothed n painted :/. Im no greennut, but renewable resources are great and i personally would think it hilarious and interesting to see a jeep made mostly of cardboard :P
Best of luck and remember, anything, is better than that weird riveted plastic...
