Supplied Air Mask for Painting?

[Jes Andersen]

Although my current project is not of the OD variety, I have some painting to do and after looking at the various types of paint using activators or hardeners, am wondering about a supplied air respirator. Years ago, we painted with just a half mask but paints have changed. I don't have a booth and would be painting outside. This one is construction equipment but I do have a couple of M37s ready for a repaint further back in the line.

For those of you that use supplied air masks, what do you have and what are your opinions of the setup? I did a search here and on other forums and the results are all over the place.

Thanks in advance for any feedback
