The Kami fluid has arrived and I had the chance to test it out. To cut to the chase, I will be ditching the Gamsol.
There was no feeling of oiliness with the Kami fluid. On trying a few drops of fluid on the skin, the Kami dried very quickly and left no impression of residue. The Gamsol took significantly longer to dry and left a greasy feeling (as if one had applied moisturiser). The scanning process seemed more straightforward too - it was much easier to eliminate small air bubbles with the Kami flui compared to the Gamsol. And once done scanning, the negative dried very quickly - seconds as opposed to having to pin it back up to dry with the Gamsol.
Hope this helps people who may be considering wet scanning fluid alternatives.
