do anyone ever use silly putty for painting multi color camo?
since this is my first time ,I need a feedback.
do silly putty harden into solid? is there any chemical reaction when contact either by water or thinner?

I can only say for,what i believe, is mostly the same thing- TAC Patafix, and it does not harden, and actually goes soft when exposed to heat (it will set if left a long time). No chem effect experienced when painting, if it leaves a residue, simply pick it up with a rolled ball of the same stuff

Yeah Silly Putty is excellent for doing multi-color camo schemes. Like Matija pointed out- there are a few brands which sell the silly putty under different names. I've never had it react with anything though I'm careful not to spill any solvent or glue on it just in case. The only thing you need to be careful about is when it comes to photo-etch- it will easily engulf it and tear it off and it will sink into the slats on photo etch grilles and pull them off. So I would say try and avoid using it around areas where there is lots of photo-etch. I also find it will kind of 'sink' or droop off a model if it is hanging down the sides and is left for a while but I usually remove any of it as soon as the paint is dry.

Karl has addressed the key issues I have with SP... so, I don't go near the stuff!

I use cheap made-in-China "art tacky" - roll it around to get it warm in your hand and a little soft, and then stretch it out into a sheet - it will stretch and pull like a scale pizza dough! Fit the tacky skin to the build and form it gently over everything - even around delicate bits and PE. It won't run, sag, or crawl away under stuff like SP. Otherwise, much the same - easy on, tool it to get whatever edging you like, spray, and pull it off - and use a little ball of the stuff to police up bits and residue, if any.

See the below Finnish BT-42 - the stuff is so easy and quick I shot all of the camo in one sitting of a couple hours, going smallish area by smallish area! (FIRST time I ever used any such masking stuff! )

Watch out for seepage where PE is concerned.

Don't be .... Silly

Use White-tac, (Blue-tac, poster-tac, etc) the white version of the stuff used to pin posters etc. to the wall.

It isn't as 'sticky' as blue-tac, rarely reacts with acrylics, stays where you put it, doesn't slide down the wall, doesn't leave residue, can be left on for weeks (in temperate climates) & is a lot easier to work with....

It can be rolled into very thin sausages for camo edges for example.

I too use poster putty. It's much more versatile than Silly Putty. cheaper (get it in the dollar store) and doesn't have Silly Putty's dangers on a model.

i used it a few times without any problems.
