Ok, a reference to one of my oldest daughter's favorite cartoons, but in this case it is my promised make your own zimeritt lesson. I use a product we have here in the states called "Quick Wood" it is epoxy putty used for repairing wood. It is softer and easier to use than, say milliput and much much less expensive. I bought my tube at Fred Meyers here in the Seattle area, but you can get it at Home Depot, Lowes, Ace most places that sell DIY home repair stuff. I read this technique on Missing Lynx originally. Not sure who posted it, but it is their idea not mine 🙂 I have a non stick cutting sheet, some talcum powder, and I knead a small ball of putty, roll it out then press it on the area needed. Note it is hard to do a large area all at once so I do it in bits, cut it square then butt the next sheet up against the last one. I use a cut down bottle top for the fine hull zim, then a home made wheel for the turret.
Tiger Is seem to have finer zim on the hulls and more coarse on the turrets. Really thats about it. I trim the excess like one would trim a pie crust, running a knife along the edges to get any "flash" off and leaving a square edge. Oh I almost forgot, you must wipe most if not all of the talc from the side you want to stick to the tank. The type of putty I use is pretty sticky, but the talc negates that so cleaning is a must!
