Mr. Champaigne,
Please allow me the liberty of introducing myself via this email as I would appreciate your help with some education on classifying grit size.
I am a corrosion engineer working at Kennedy Space Center and currently have some oversight on a depainting and coating project.
I have attached a spreadsheet <> that hopefully you can follow so that you can straighten me out.
Please feel free to call me for discussion as I think I need it.
Sincerely and thank you,
Joe
