Thanks Kerik for the info re: booze as a smoothing agent. I think I will give it a try...on the rocks!
I can attest to the smoothness of your images having seen a great display of them at 8 Elm Photo in Toronto a few years back...truly outstanding work!
I may have been thinking about polyvinyl alcohol or some such beast. I remember reading about it on the Bostick and Sullivan site a while ago.
I will be doing some printing this weekend so I think I will give the ethyl alcohol a try...on paper that is. I will probably stick to single malt in the glass.
