Blind Mark xt and outlet box location

[sgf13]

My electrical contractor began work today. So far all I have in my metal shop is the breaker box and my four outlet boxes and already I wish I'd done something different. I am going to partially cover the walls with 1/2" BC plywood. I already wish I'd have done that first then had the flexible conduit and outlet boxes just mounted to the plywood rather than hidden behind it. I didn't so here goes my two questions.

Does anyone know if the Blindmark xt box locating tool will work properly with 1/2" plywood?

Second question, they installed the plastic outlet boxes flush with the metal studs. That will leave the boxes flush with the back of the plywood and not covering the box cutout edges of the plywood when plates are installed. There will be an electrical inspection but shouldn't the box protrude a 1/2" from the studs to cover the plywood edges?

I've never personally used one, but it says here that it can be used for plywood:

As far as the flush with studs is concerned, the Code is that it will be flush to or project from any flammable surface (aka the plywood)

Thanks. I looked the website twice and overlooked where it said "plywood".

I accidentally said "plastic" outlet boxes instead of metal as I should have. I learned that there are extenders that fit these boxes and the will cover the plywood edges.
