I have a Battlefront armored train locomotive and some of the parts do not sit flush with assembly even after the typical sanding and filing to make them fit due to defects in the parts. What kind of gap filler will work with both of these materials? I've never actually used one before |

GW has liquid greenstuff. I have heard white glue works as well. |

Greenstuff or Milliput. The latter in superfine white might be your best option since it can be smoothed very effectively and rubbed down when dry. Otherwise I'd look and see what's available as filler specifically sold for model kits. |

Milliput What color? This is a 15mm scale train and some of the areas will be difficult to sand afterwards, I was afraid greenstuff would be too difficult to work with in such areas. |

I would superglue a shaped sliver of MDF or good cardboard into the gap then glue next part onto the sliver. For a gap filling glue I use two layers on contact adhesive and a brushed on superglue layer. The contact adhesive fills the gap and the superglue provide the strength. |

I use 'Golden Gel Mediums Molding Paste'. Dries fast, thins and cleans up with water, can be shaped with wet paintbrush, no scent I can smell. Does come in 'lifetime supply' sized jar (maybe not for you young'uns) and drys fast (add a couple of drops water to jar at each use) |

For resin you have the widest options. If it is just cosmetic and does not need to add to the structural unity of the union, I suggest simple solvent based gap filler. That would be Squadron Green Putty, Testors Contour, and Tamiya Basic Type. These are low cost easy to work with and can be had at most shops that sell kits. These are the same stuff a auto-body-filler of old. This being called Bondo 907 Glazing and Spot Putty these days (I think) link These solvent based fillers shrink a bit, which can be a good thing or a pain, depending on your situation. Other options include water based fillers, and epoxy glue type putties. This article covers the options pretty well: link

I've had good results with PC-7 epoxy putty and superglue gel mixed with talc (baby powder). "Perfect plastic putty" works well but the fine applicator nozzle has always clogged in short order (at least for me-- other modelers swear by it). |
