Chemical treatment to approximate a beadblast finish on stainless steel

Q. I've recently designed a 304 stainless steel pavilion for a garden. Prior to installation I had the parts bead blasted. I was required to weld the piece together on-site and now I'm trying to match the welded areas (that have been ground and sanded smooth) to the bead blasted areas.

I'm having difficulty getting anyone to come on site and touch up the bead blasting and so I thought there might be a process that can approximate the finish.

As it stands now the random orbital sanded areas are close to the texture of the bead blasted areas, the sheen is just a little off; a bit too shiny.

The attached images is ground but not yet sanded.

Thank you

A. Hi Brant.

If you can sand it to match, that would be great. Otherwise, bead blasting on site may be the only alternative. I really don't think you'll match it with chemicals.
