Out door sign

[PPD]

I am doing my first large outdoor sign. The front layer is gonna be stainless steel but behind that is gonna be a powder coated piece. My question is for longevity should the powdered piece be stainless steel or just regular steel? does it matter either way?

Thanks

The powder coat will protect regular steel just fine if the steel is clean, rust free, and prepared properly before coating it. Would love to see a pic when it done!
