I ran into Pro products in Oregon, Washington and Idaho when I was an Outside Sales Rep and Trainer for Meguiar's.
Like all lines there's bound to be winners and dogs in the line. When it comes to paint correction, the most important variable that will make or break a brand name is the abrasive technology used in the correction products, i.e. compounds, polishes and waxes.
Being a body shop they should be using all or most all Body Shop Safe products unless they have a dedicated area for doing detailing work or unless they've created their own work-arounds for contamination issues, like a top quality downdraft paint booth or adding fish eye eliminator to their paint system, etc.
Good luck, hope you get the job and then have the opportunity to do full wetsand, cut and buff jobs and of course share them on our forum.
