Had the deluxe hood of my 67 mustang media blasted,was the dust less low psi 60lbs,crushed recycled glass was the media,hood seems to have small waves in it especially where the support braces start and end.never noticed it before, the blasting company doubts that they caused it, my question is how smooth/flat where the hoods from the original day they were installed

Never noticed or had the top exterior surface of a hood like you describe

A friend of mine had his used, replacement '70 Buick GS Stage I hood and fenders media blasted somewhere in the commercial district 30 some years ago. The hood was rare then.
He assembled it and sent it off to the painter.
Painter called and asked if he wanted him to continue as he was getting sea sick from looking at the waves in the hood and fender.
He had them painted anyway and every time I sat in the passenger seat I got a little nauseous.
Overheating the metal by using too much pressure, wrong media or a giant fire hose of a nozzle causes this. Some blasters will only do one side of the hood.
The stock hoods are nice and straight.

I've been blasting away for more than 25 years and have not had any large sheet metal items "distorted". I think who ever is doing the work needs a slap across the head and some retraining. My time is not "pushed" which may be part of the difference.

While I am sure that Jeff has seen a lot more Factory Mustang hoods than I, I have not seen one, Mustang or otherwise, exhibiting "the Wave".
I agree with Jim's comments. I had my '57 Ford Retractable sand blasted in the mid-seventies. notice that I said "sand" blasted, not media blasted. That is because "back then", there was no glass bead, walnut shell, soda blasting, etc. being done. The outfit that did it for me asked me to chemically remove as much of the top layer of paint (I had the car repainted in the early 60's, before I started painting myself) that I could, as they were concerned that blasting two layers of enamel might cause warping of the broad areas of sheet metal (even though the sheet metal was of heavier gage at that time. Even after I did that, they said they had to be very careful as the original Factory paint had almost been "rubberized" over time. Bottom line, it turned out fine ; no waves, blow throughs, etc. Back then, as Jim noted in him doing his own, people weren't "rushed".
My only complaint was that for years, and even to a smaller extent even today, almost 45 years later, I was vacuuming and blowing sand out of nooks and crannies that I had done before. Which is why I decided in the late 70's that I would never have another cfar body blasted ; only those parts which could be removed and thoroughly cleaned. Ihave done several cars, and parts of cars since then, and if they had more than just the original Factory paint (which can easily be sanded, primed and painted), I have used Aircraft Stripper ; a little messy, but better than having blasting media appear for years.
Just my personal experiences.
