Were I you I'd probably just wire wheel the front strap or since your such a patient and detail oriented guy, use a triangle file to clean up the front strap. A checkered front strap is a wonderful thing, be nice to keep it sharp and useful even on a BBQ gun.
They make checkering files for metal if you can figure out the line per inch.
