In my experience, the original Silly Putty trademark (the children's stuff, from Crayola!) works better than the "fancy" versions designed specifically for masking in scale modeling. I tried two of the fancy ones (Mr. Hyde Masking Putty and another one that I can't remember; both were black), and both produced a lot of stringy lines that were very difficult to control. If (when!) one of those strings falls on fresh paint, there goes your paint job. The original Silly Putty can also produce strings, but much less than the fancy brands specifically designed for scale modeling.
Hello FSM, i just watched this video the first time and was wondering if the masking trick with silly putty can used when a solvent based paint? Enamel and or a Lacquer? Just wondering if the solvent will react with the silly putty. This is Aaron was using Vallejo water based acrylic. As always thanks for these tip videos.
The silly putty I bought from Hobby Lobby isn't very firm and "shifts" almost immediately as it settles. Is that normal with it or did I get a bad batch of silly putty?
In most cases it doesn't leave any residue. However, I have found a weird discoloration after I apply the Silly Putty over some Vallejo greens: 71.286 IJA Olive Green and 71.332 IJN Black Green. I just repainted the affected areas, although maybe the effect would have disappeared after a layer of varnish --or maybe not! Also, I once got a can of Silly Putty that looked very greasy, almost like peanut butter. I didn't want to take the risk. I just threw it away.
