i'll show everyone how to make styrene putty an old modeler's trick first you need testers liquid cement and fill up the bottle about that much cut you up some sprue i like to use the colored ones just chop you up some sprue put it in it takes about a day for it to dissolve and doing the color ones you can have so you can see what you're putting on the model when you use styrene for a putty it won't sag or no dips like tube putty does and you can do different thicknesses excellent gap filler and if you need to thin it just add more liquid glue to it it's a simple simple little trick and a great product to use so
