I would say check out your sanblast guy before taking parts to him , I did a little background check on the 2 local shops in my area an found 1 was terrible the other nothin but good words ....so I stopped in an talked to the owner , an I told him what i wanted done ...he said he done Lotts an when he told me he would not touch the underside of my hood but would blast the top side an explained to me how the reinforcement ribs under the hood when blasting around them is a very tricky process and he couldnt gaurantee against warping it, I knew I had someone with expierience....fenders doors & hood came out very nice !
