Congrats John. Alternative processes are great fun. I recently started gumprinting and it's much more creative that traditional darkroom work. Keep up the good work and amaze the masses!
Using a face solarium with this neg takes between 9 and 18 minutes depending on the paper I use. In this case it was a short exposure on acrylic paper which has a heavy surface size and great contrast. Sadly not archival though.
Argus, I too do gum and all my negs are souped in Rodinal
