My 1st try at zimm., I also used tamiya polyester putty. This worked pretty good useing the tamiya zimm. tools. I have used tamiya type tools and some stamp type tools I got years ago somewhere. My biggest problem with this type is the fumes-I have to use a mask, and outside with the rest of the safety precautions. I've used Cavalier zimmerite sets,[much easier]. I have also tried an engraver, and drimmel tool.These, I need much more practice on! I known guy's who do it this way and you would never know it.
My biggest trick is to practice on something expendable like an old project, or a "closet queen" before trying it on my newest or best kit. I agree with moses, It's just a matter of what works for you. Good luck!
