well i have some surface rust in my engine bay and prob some on the rear quarters (but havnt sanded the quarters back yet so not sure)anyways the bottom of my tray is pretty much packed full of rust but i dont want to be cutting it out just yet. im going to get it on the road stock and then in a yr or two and a few more dollars start looking at other mods. So the back tray has a kind of "chicken pox" look to it in areas. Some of the dots has even rusted clean holes straight through :S. But because i dont want to be cutting chunks and chunks of rusted metal out here there and everywhere im going to try and cut the worst parts out and jest weld over the other and fix with either bog or some more stronger stuff like fibre glass bog i think? anyways all suggestions, opinions and help much appreciated!! cheers
