Removing the old paint “edges”

The sky is the limit. HF equipment will work for a while but you will probably spend as much time keeping it going as you will blasting.
I use a Sullair 375 and I have a couple different Clemco pots for using multiple media’s.

I started out with an ALC pot running off of my shop Quincy 80gal 17.2CFM compressor and it did the job.

You have access to a great high CFM Diesel compressor, that’s the only way to go. Just keep pressure down.

I’m sure more have experience with other equipment.
