Back to HH Blackshields! FW Warlord Titan. Also Dark Mechanicum/Battlefleet Gothic.
Starting with the head.
Head was fairly simple to assemble. Has a very detailed interior. Had to heat the pipes hanging on the bottom to give them a better fit. Also used liquid greenstuff to fill any gaps in the joints I wasn’t happy with. I prefer liquid greenstuff to the regular stuff because it’s very easy to sand/file back on flat surfaces. Only issue with it is, it dries by evaporation so you get shrinkage, so you have to do multiple fillings.
May I suggest Vallejo Plastic Putty (70.401)? That come from a tube and shrinkage is minimal. Plus, the fine tip of the tube makes it easy to apply in tight spaces.
Can you sand it? ?
Yes. It’s acrylic and you can squeeze it from the tube, smooth it with water and when it’s dry sand the rest. It’s a god send for small but noticeable gaps. And since it’s water soluble excess can just be washed/brushed of as long as it’s wet.
Or milliput which is probably cheaper and just as good
Does milliput come in a tube with fine tip nozzle? I’m sure it’s the better putty but the Vallejo is just very easy to use. Ready to use, just push in, wipe off and be done. Though I need to test milliput some time myself
