What is your favorite technique or product for filling in large seams with multi-part plastic models, when pieces do not fit seamlessly?

For example, a two-part torso with large, sunken seams.

Green stuff.

Magic sculpt. Thins with water and cleans up with water. Once set, it is rock hard.

Superglue (mix with baking powder).

Auto Filler.

Plastic (card, Sprue, scrap – glue in place and carve/sand flat).

Milliput or Squardron Putty.

Second superglue. If you cure it with accellerator, it stays soft for a bit, making it easier to sand. Sometimes I'll build up very bad seams with epoxy too.

Squadron putty works great.

Use either strip styrene or the like to fill up the majority of the gap, then I often like to use Formula 560 (which is often called canopy glue) but is a very thick water based glue (think really thick elmers) that is non corrosive to plastic. You can smooth it with your fingers, and clean up the edges. It will dry smooth, if you've been careful, i.e. keeping it off the rest of the model, no sanding is necessary. Add additional coats if necessary and it will make the join darn near permanent.

Liquid green stuff

Mr. Surface 500 is also very good but very hard to get in the States.

Green stuff originally though I've started using this modelling paste stuff I got at the craft store (originally for bases).

It's much easier to shape than green stuff as it's much softer and more pliable, it doesn't stick to everything and it basically turns into cement when it dries.

Milliput for me too

Milliput, giving it a wipe down with a wet tissue before it cures gives a smooth finish and saves on a lot of sanding.
