Milliput Epoxy Putty from Wave is just the ticket for filling seams or sculpting parts for your plastic model kits and garage kits. Grade S is very fine-grained. This stuff won't shrink, takes between two to three hours to harden, sticks to what you're working on like crazy, and is perfect for thick 'n' heavy applications. To use, just cut equal amounts of the two-part putty, knead together thoroughly, and start working. Brilliant stuff! Made in the U.K. by the Milliput Company. 113.4 grams.
