Im not arguing. I have done a few cars myself as well.

Of course my advise is vaild if it works. dont take my advise as gospel...if the pit has certain characteristics where the wire wheel wont work...then Id move on to the blasting....Id NEVER leave any rust specs on there...but I always like to start off mild b4 going WILD on everything I do.

oh well, guess you get my point.

If this is not clean enough, I dont know what would it be...this is the hood for my 69 original HEMI Charger. 3m abrasives pad on a drill and the infamous fine bristle wire wheel. I dont see any rust specs on it. Not a single wavy spot as well. get my point? why blast it if its not necessary?

It makes me cringe when I see people blasting good nice original outer sheetmetal panels to remove paint and or superficial rust. Same deal with high speed sanders that leave deep scratches on sheetmetal that not even a light primer coat will fill up.

by the looks of the sheetmetal finish on mopar 394 seems he used an orbital sander...thats That wont damage, nor heat up nor warp sheetmetal.
