Helpful Hints
Both cast bronze and cast brass letters are protected with a clear protective coating prior to shipping, however, cast brass is not recommended for exterior use.
Although casting alloys of aluminum can be anodized, because of the inherent nature of the sand casting process, an anodized finish is not recommended for cast products.
