I don't think it's quite as sticky as GS. Definately not too sticky if wait a while to put it on. Gs, to me, is ANNOYINGLY sticky...but that's just me. The resin "half" of MS is pretty sticky. The hardener half isn't hardly sticky at all. Once mixed, it has a bit of a greasy/wax like feel to it. Most noticeable right after you've mixed it. I've gotten into the habit of washing my hands right after I mix some up. The more you handle it, the more you will notice it but it's not that bad. It will make your fingers a little tacky though. MS seems to have a tendency to not have a great grip on itself. For instance: If I decide to add a layer on to something that wasn't quite built up enough. Once the second layer is cured, if it's a thinner second layer, it sometimes won't carve well without trying to lift the whole second layer....did that even remotely make sense? Of course, that may me due in part to the first layer being sanded/polished smooth so it doesn't have a lot of "grip".....
If that didn't make sense, just say so and I'll go to bed and try again tomorrow lol! It's been a long hot, no A/C day......
