I have ordered the 4 ounce bottle of 321 and need to know about its viscosity. Is it water thin or like conventional reel oil? The proper needle size will make using it easier. Thanks to all.
It is a light oil similar to machine oil. It will flow easily through a needle tip.
I get the needle tip bottles from Amazon. They have different gauges of needle tips to choose from.
If you are buying TSI from Dawn @ Smooth Drag, she also has small needle applicator dispenser bottles for sale.
