You asked about AM photoetching or something similar that would fit this model?
I have the same model and got the PE Zimmerit for it. I do NOT like it because it's hard to make damage and flaking look real. I got the ATAK Zimmerit for my Panthers and it is much, much better and much easier to work with. In fact, it would make a Tiger F13 type of model very easy to make with 1/2 or more of the Zimmerit gone. I've been planning on making my next Tiger like that, with most of the Zimmerit gone
