Tamiya Putty White

This is a very good putty. It will fill small holes thru a body without needing a backing piece of plastic inside. It will also fill large areas with no problem. If it is applied in a thick coat you may get some shrinkage. Where it needs to be thick, it is best to apply 2 or more thin coats. The grain is very smooth and sands easily, but it should be sprayed with primer before painting. Some paints such as lacquers will cause it to shrink if it is not protected.

I use this and Tamiya Basic putty every so often for gap and seam filling. (use the basic on gray plastic, white on white plastic, etc.) It's pretty easy to apply. There is a minor amount of shrinkage when it dries which is made even worse by using lacquer thinner. I just use it straight up out of the tube. It's got a very strong smell so I recommend using this in a well ventilated area. For heavy jobs i typically use a little milliput, followed by tamiya putty, And then if i need an even finer coat I finish up with some Mr. Surfacer. The Tamiya putty is really easy to sand so go carefully as to not remove too much.

This putty is actually pretty soft and easy to sand. There is a strong odor but it's on the level of paint odors. It probably won't kill you. The putty does shrink a little after it cures which is something to keep in mind. I would use a bit too much putty, and then sand it down. It sands easily so that's not a problem. It's nice putty for seams but not so good for large fill-ins.
