I have wanted a Marmit Sandtrooper for years and your collection makes me jealous as hell! Awesome figures and photos too!!!! Ive been droping hints to the missus for a Marmit TD for Xmas, they look very accurate but still have plenty of scope for customising, which I love doing.
Did you strip the original dirt and re-apply your own? It looks nicer than the stock weathering I have see on others. If so, how did you remove the original weathering?
