Powder coating = engine rebuild

One of those SeeSnake Micro Inspection Cameras from Home Depot or something similar from a plumber buddy would be good before the final button up of the intake...

My coating guy is going to blank off the openings. He's going to wash it afterwards anyway. Twice. I'm going to wash it again, and inspect it thoroughly.
I had an experience many years ago with grit in the works. A clumsy mechanic broke off a spark plug and pieces fell down inside. He used an air line to blow it out, but the intake valve happened to be open on that cylinder so the grit blew into the intake. All four cylinders got chewed up. The shop denied that this is how it happened, but there was no other way. Change spark plugs = new engine? No, but there's a special need to be careful with spark plugs that some may not recognize.

I removed the factory top-coat on my '90 GT intake with plastic scrapers. Took less time than trying in vain to remove abrasive from hidden parts of the intake. Rattle can molten silver wheel paint looked good enough for me.
In my opinion, the risk isn't worth the reward...

Too much "here's the way I did it, therefore it must be correct".
The point is simple. Regardless of your methods, who does it, how it is done...anything left in the intake system goes directly into the engine and can cause damage.
Make sure your intake is perfectly clean.
Done.

Amazing all of the hysterics over this..if you miss "cleaning" in any motor assembly step, you're asking for a problem.
Just CLEAN things...

Is that factory finish really a powder coat? I'm surprised it flakes off so badly, even after this much time, if it is...

I'm curious now about the factory intake. Does it have ANY kind of coating on the inside of the intake? So, in other words... are these people removing and recoating the insides of the intake because the factory did? Or is the problem the poor procedure of the removal of the exterior coating that leads to debris stuck on the inside?
My car was already done by Alex "Ghandi" Gandeski; the previous owner. In any other case I might be worried... but if any or you know Alex... You know it's CLEAN! :P

But either way..it was cast in sand, and then _cleaned_.
It's not that hard, it just needs done. WAY too much doom and gloom in here over cleaning something.
Some versions are harder than others, and will just require being blasted a different way.
