I took what I think is the heaviest gel medium for a test run (the local store had Schminke "Acryl Modellier-Paste, fein", other brands may vary of course). It has about the same consistency as Vallejo putty, and can be worked the same way. Once fully set (and be aware that this takes a few days), it is rather harder, and shows no tendency to peel off, eliminating my main problem with the putty. It sands down absolutely smooth. Whether I can get it to work for fine detail sculpting is a question that will have to wait to a much later date. I have some hope though.
I also tested Liquid Green Stuff. This is very comparable to the acrylic gel, except that it is much stiffer, and thus easier to sculpt into a shape. At a guess the green stuff would be best for moderate to fine detail, while the gel could be used for the finest of detail work, as well as as cheap (11 euro for 250ml), non-smelly general filler and for surface treatment on large parts that have rather coarser surfaces than one might like (short run or resin kits..).
