Did you look on ebay for Dykem red dye? I bought some there a few months back.
Believe you will want to go over the shiny silver. If you have some with gold, it can be removed to expose the clear zinc base.
For reference:
Dykem 81496 is red and TRANSPARENT - this is the stuff that Jeff has been using and has apparently been discontinued by Dykem. This should have been a good coating for clear zinc or zinc dichromate to make it look like zinc red dichromate.
Dykem 81491 is red and OPAQUE - this is the stuff Perkins Restoration said that was a good match for zinc phosphate S100.
On Ebay:
A search for "Dykem 81496" turns up a single result: GALLON JUGS of OPAQUE staining colors for $279.
A search for "Dykem 81491" turns up a bottle and a jug of the OPAQUE red stuff. Don't need that, just checking anyway.
A search for "Dykem transparent red" or "Dykem red" turns up red LAYOUT FLUID (not the same stuff) and other things, but no 81496 or other TRANSPARENT red stains.
A search for "transparent staining color" returns irrelevant results.
You can't get the Dykem transparent red staining color any more.
