hi
Ilooked into the stick-on zimmerit when I built my tiger but I thought it loked a bit too uniform, so I went down the milliput route. I spread milliput thinnly onto the tank in small sections, then gently pressed a flat bladed screwdriver into the putty to make the ridges. It took a bit of time but I think the end result was worth it.
remember to post pictures as we all love 'em!!
