I think the biggest advantage is time savings and blasting can get intio areas you can't reach with sandpaper or a wire brush. I do think it is very beneficial to strip to bare metal to get rid of so much paint build-up and to uncover what work previous owners may have done incorrectly. I stripped my 66 by hand as much as possible. Takes a TON of time to do it this way, but I don't have the $750 to have it done. My time is free. I used some checmical strippers and it works fairly well, but I've found a 80 grit paper on a DA workd much better than expected, and I use a wire cup on a 4 1/2" grinder to get to other areas where the DA has trouble without tearing the paper. Could always use a Harbor Freight $69 sand blaster to get into the last of the areas yourself to finish the job if you wanted.
