Hi,i am new in signage works,so can anyone explain the way to paint the engraved portion (hatched sign/letters) on brass.I also want the type of paint to be used since its is a outdoor signage
but here are a few links to get you started.
you could try using a clear contact like used to cover books on the brass before cutting the design, this will mask off sections where blackening isn't wanted.
Try a small sample first! .....i'm not a sign maker by any stretch of the imagination!
