Has anyone had any ISI air packs flow tested or repaired? I have a customer of mine looking for repairs, and I figured you guys could point me in the direction of someone respectable as this isn't my area of expertise. Preferably in the Detroit area, but if they have to go out of state to get trustworthy service it's worth it to me.

They've got some MSA SCBAs that need looking at as well, any advice here for the Detroit area?

I guess it's worth it to ask if there's anyone in the Detroit area I should actually avoid as well.
