FIXIT Epoxy Clay

The most versatile epoxy we've every found. With it: make perfect fin fillets, fill spirals in tubes, thread locker, fix imperfections and gaps between mating parts. Even use it to make blast-deflectors in two-stage rockets! It doesn't run, or sag, and it cures rocket hard. You can sculpt and sand it too. Try it once, and you'll discover that it has 1,001 uses around the house.
