thanks for the info. i saw that link last week and thats what got me up to trying the zim again. using the razor holder for the zim tool is a great idea, but i found that using the two diffrent putties was a pain in the rear. trying to get them to just the right thicknes was hard enough, not to mention working quickly so that it didnt dry up and then to make the markings on top of that. its not an easy task. anyway any idea what craft stores,i tried looking at some of their web sites and didnt have any luck finding the milliput
