Strange you should mention that....
Two things I swore I would never do is have a green Jeep, or one of those butt ugly four door Jeep wanna be's.
(I'm so ashamed now) :D
I've got a couple old dented up fenders here you can have, if you're wanting to practice some sheet metal welding before attempting the bob. Othewise, they'll hit the scrapper.
I did Redwood after my Heep fell through it. Pricey, but you'll NEVER replace it.
Trex, and the other plastics aren't stong enough without a bunch of additional bracing.
Lots of "Boiled Linseed" oil once a year. Takes 20 minutes, tops. Do it in a dirt area, where it can drip through.
Or, just replace the deck every 5 years? Mine's almost 20 now.
Macco.....
Oh, wait.... :)
Seriously though, for a basic shoot why not? They did a really good job on the wife's a few years ago. Just don't plan on getting a good paint job for $179 though. I think I was into that one around $1300.
