Armada was my first foray into painting or modding tabletop minis, so I've never tinkered with gap filler. However, I think I'll pick some up to zap the seams on my CR90s, MC80s, and Hammerheads. What kind do you recommend (liquid, paste, I don't know)?

Games Workshop makes a product called Green Stuff. Other modelling companies make a version of it too but I know less of those.

Green stuff comes in either a liquid paint on format really nice for very thin cracks and seams. The solid putty version is better for large gaps or even sculpting your own details and features.

So for these teeny little seams that interrupt the smooth hull structure, I can squirt a little liquid green stuff into the gap and then paint over to match the surrounding area?

personally I prefer Mulliput, more stable and cheaper than green stuff (which is, well, GW-priced).

security advice, always prepare and use those in a well ventilated area (outside if possible) and wear gloves (surgical thin one are ok) ... It is more than mildly skin-toxic, possibly carcinogenic, even if it's not bad-smelling

if you want safer filler, use glazier mastic, only problem, it can take several month to settle

I did not know it took that long! If I was a go getter I would stay away from that, but I'm not and it sounds like the perfect amount of time between me assembling and me painting.

It's in a little paint pot like other GW paints. So it would require a brush application or swapping it to a dropper bottle. But Yah, just draw a thin line of it onto the seam and let it dry. May need to do a couple thin layers to build it up flush with the surface. After that sand and prime/paint and enjoy!

in very wet weather conditions it can... Usually a pair of days are enough anyway, remember to lightly sand it afterwards. but it's the only filler that can be eaten without problem (a good choice if you have very young kids around! Taste is bad, so they will not do it twice)

I get the notion that what you said would make some very twistedly humorous ad.

Bondo usually does the trick for me; it's an automotive filler putty, if you're not familiar. It's been safe on every plastic I've tried it on, usually dries hard overnight, is sandable, and takes paint nicely. The consistency is usually rather thick, though, so it made hide small details if you're not careful during application.
