I was gonna say to be sure and use a guy that knows what hes doing ...sounds like you got that covered..
I weighed the time vs $$$ on my IH build...doesnt take long to decide that blasting was the best option..
They can get into all the tight spots I couldnt..other than my doors, it was money well spent..I could drop parts of in the morning, pick em up in the afternoon..wipe em down and spray em with epoxy by dark..
If you do get them blasted be sure to get some epoxy primer on them before they flash rust..then you can do you repair work and follow that with epoxy as you go..
They used coal slag on mine..
