I have used this product for precise work and found it very useful. Also using it to stick half drilled beads to silver earring post and left it longer to bond they held extreamly well. Every use I wipe the nozzle and when the finished session wipe the needle with gin to clean. The down side - used to glue silver collets which I couldnt solder, it was fairly easy to pull apart when needed to. A very good product.
