Making Filler With Sprue And Cement

     Often I can be found at my bench experimenting with this technique or that. Usually this is motivated by a desire to avoid spending money on brand-name products. Why empty your wallet if you can use ingredients from your own stash of modeling tools? It's the classic recipe of utilizing leftovers.
     This morning I decided to try a trick I'd read on the internet. Some hobbyists use a filler made of leftover sprues and an old jar of welding cement. The sprues dissolve into the liquid, making a gooey putty. With care, this can be applied to seams, allowed to dry, and sanded as with any other filler. Check out the pics below which illustrate this straightforward process.

The ingredients. Any old sprue will do. ;)

I mixed two leftover bottles of cement. The Testors bottle, with its wider  opening, was well suited for use as a container. You can even use the brush in the cap to apply the product later.

On the stirring stick, you can see evidence of the liquified sprue after only a few  minutes of soaking.
