Hey Mayhew...I won't get on ya for not doin the zim yourself bud. Actually zimming Panthers is a bit harder to do. As for teh decals...I suggest using either stencils or dry transfers for the markings. I know you said you have tried Archer transfers..but maybe this will help better Archer ( http://www.archertransfers.com/ ) are great for zimmerit. I personally never use water slide decals, except if I can not find an alternative to teh marking. You will find that applying water slide decals to a zim very tediuos and stressful in my opinion. Archer offers a nice 8 diferent sets of Panther Dry Transfer Markings...and one set that has them all. I highly recommend them. Here are some direct links to these markings with the marking below the link...all are perfect for zim..
