There are 2 major factors that play into applying Zimmerit. For one, most modellers are afraid to try it and ruin a 40 dollar kit. Also, many feel they do not have the necessary toold to simulate it. My suggestion is to always practice on an old model or a piece of plastic card. As for the tools you will need. I highly recommend Tamiya's Polyester Putty (man I sound like a broken record
). It has the consistency of a filler putty, but the drying time of an epoxy. It spreads nice and thin and if you don't likt it, you can take it off with no effect to the kit. Epoxy Putties like Milliput, Duro or A+B force you to score or sand the surface of teh model for better adhesion. You also need to use a copiuos amount of water to keep it workable and you need to think it out. To much trouble in my opinion. The next tool you will need is a rack to simulate the ridged pattern. I use Tamiya's Zim tools with a large X-Acto Blade handle. It works great and I can Zim a whole model in about 1 1/2 of modelling time. If you can not find the Polyester Putty then I recommend Zim-it-rite. It is very much like the Polyester Putty and it can be ordered at www.rjproducts.com. Rich the owner is a great guy and will be more then happy to help you. You should be able to order the Tamiya Zim tool at any local hobby store that carries Tamiya products. That goes for the Polyester Putty as well. If you can't get hold of the Zim tool, you could make your own from a razor saw. Here are 2 pics of some Zim work that was posted on these forums using the Polyester Putty and Tamiya Zim tool.
