I have seen people mention how sand gets everywhere when sandblasting.I want to do the underside of the hood not the skin sheet metal just the inner structure.I dont want sand between the braceing and the skin I would never get it all out. I'm thinking I could use spray foam to fill all the hollow areas to keep the sand out. I could tape off the sheetmetal with cardboard. See any problem with this.? I did the radiator support only took half an hr. and looks great.
