Hoping this twelve year old thread can be momentarily revived.

Assuming the KS gauge fluid one buys nowadays from outfits like Straight Eight still fades like it did in the past, I am thinking of dyeing the fluid with Sudan Red and am wondering which Sudan Red dye was used - there are several. Perhaps it was Sudan Red #1 ?

Also curious as to whether the dye held fast over the years. Still red?
