[NJARC] DIY flux comes straight from the tree

[Thomas Lee]

It didn't go through the first time... if you're interested...

Summarized...
If you're lucky 
enough to find a large dollop leaking from a pine tree, leave a container along with some 
isopropyl alcohol. In the morning the sap will fully dissolved, run it through a coffee filter to get rid of any debris.  Keep it in a 
small jar.
