I have never seen or heard of such a device in all my years being in the coatings business! pffft!
Epoxy primer has the ability to encapsoluate small bits of rust that are even visibile to the naked eye, so using a device to see microscopic bits is full on fraudulent.
Many coatings require a minimum of SSPC SP2 or SSPC SP3 which is mechincal removal of rust by hand or by machine. This is not even as good as sand blasting!
Here is a full description of the different standards of metal prep. Take a look!

I'm curious to know if they used a chemical metal stripping or prep like paint stripper, acid, vinegar, or witches potion that is causing the failure??? So many failures are caused by these short cuts.
