Just a quick question, how do I prevent rubbery parts such as ROTF Ravage's spikes / ROTF Leader Class Megatron's killer arm from being sticky / tacky after painting / spray-painting it?

And to rephrase it in better (maybe worse) English: How do I prevent rubbery parts from being stick after I paint it, an example would be ROTF Ravage's spikes or ROTF Leader Class Megatron's killer arm (claw).

 

if you are using Enamels, you need to put a layer or acrylics on the part first, after that dries, when you spray it the paint will adhere to that and you should have no stickiness.

this has at least worked for me on all The Fallen figures that i have needed to do this too

 

if you are using acrylics,use a super glue with a control tip brush to coat the piece.then just let it dry
