No, I'm not familiar with him.

Dario worked at the old Camtech w Peter Jeune & Julian F (who later started the camera store). He had a great exhibition on Harley culture @ Sturgis & was a wonderful portrait photographer....& a killer printer.

Hmm, don't remember him. Definitely remember Ian and of course Peter and Julian.

Craig - were you mixing a Pyrocat formula for water or glycol? The water version could exhaust prematurely.

This.

I had some surprising long term Pcat failure with a water for part A. I have never had any Pcat failure when Part A is mixed in glycol, even well after depleting the original 500ml over a 1 year + .. that is, even a diminishing amount in the bottle with increasing amounts of air made no difference with glycol based Part A.

I've never had a Pyrocat failure with the HDC, MC or HD version, but I only mix in glycol. I have had the HD version in glycol last 6+ years. After 3 of those years I mixed a new batch thinking the old batch could go anytime. I then switched to the new batch, but would test the old batch periodically and it was still good at +6 years when I finally dumped it. Damn good stuff! Yes, it's different than PMK or another pyro I use, WD2H+, but I like it much better overalll. Just me of course and you might have a different idea, which is fine with me.
