Shop air dilemma

Really anything.

If you've ever blasted anything larger than a PS bracket, that's just the way it works.

That's why I preach CFM.

Anyone who thinks they're gonna get a 3HP 8 CFM unit (even if it has two 120 gallon tanks) and blast anything successfully will be sorely dissapointed.

Huh, mine doesn't do that. I run about 40 or 50 psi at the blaster. My compressor keeps up just fine.

CFM is important, but air doesn't get the job done, the media does. If the air aint delivering the media, doesn't matter how much CFM you have.

I use a metering valve under mine and it's night and day.

You probably have a commercial unit and it may already have one, but in my case it was an amazing improvement.
