Filling Cracks and Voids

Ladies and Gentlemen



I have my trusted remedies to fill voids and cracks, but I want to get a bit more arty. I have managed to collect about a kilo of brass filings from a Key cutting shop. I am hoping to fill voids etc using the brass and make it a feature.



Now, I am not 100% sure how to do it.



1. I could fill the hole with the brass and back fill it with medium CA glue???

2. Mix the CA glue with the brass filing then fill the void????

3. How do other people do it?

Thanks
