I did along the sides on my truck under the factory body line and down to the rocker panles. I also removed my stock fender flares and herked around my wheel wells. I wish i had done a begtter job masking here because there are some stray marks...but it kinda looks like thrown mud so it is not that bad. I also did my hood because i needed to get it painted and my red has faded so much it would have been very hard to match it up. The hood itself looks good, although i think i need to add another coat cuz there is one area that is textured more than others. But i kinda looks odd on the truck...kind like the import guys that use carbon fiber hoods. Once i scratch the rest of the truck up too badly then i will just coat the whole thing.
