Well then I guess the hydro shop I used to use lied to me then because that's the info I got.Interior shot blasting does not require a new hydro. Although the only people really capable of doing it right with the correct media which doesn't remove any metal (just the corrosion) is a hydro shop. Mine has blasted the epoxy liner out of a couple of lp72s for me, way easier than burning out my tumbler with days of rolling.
