WRT media blasting, I might have to look into getting one because it would definitely make cleaning up the inside of the cookbox much easier. As to the end caps and outside of the firebox, yeah, you don't want to lose the texture. But sometimes, you come across end caps that have flaking paint. There's no way to get that texture back that we are currently aware of. So, it might make sense to take those caps down to smooth, bare aluminum before repainting. Yes, texture will be gone, but you'll have a consistent finish, not a spotted one.
