Good to see you Enzyme. The firestorm hasn't changed too much, most upgrades were minor and it certainly isn't worth an upgrade for what you have into yours. Good luck with the paint job. You're brave to post that you are going to paint....I usually wait to see if it doesn't suck.
I've decided to no longer try to paint good bodies. Monochrome from now on since most get smashed too quickly anyways (and most of my painting sucks). That being said, I still have two original FS bodies that are in great shape but that truck is an exception. I do have a friend that paints bodies professionally (among other things) and he has a new FS body coming for me that will hopefully turn out really cool.
