>>10741476Waterslide Decals, yeah. Some of them are quite thin, so if I ever attempt them I'll probably go overboard and use MicroSol/MicroSet that some Warhammer 40k folks use.
I ended up buying the limited edition set that also came with a full set of transparent parts, so sometime after I took that photo I decided on swapping in some of those to give it a bit of visual flair.
