Zap's Z42 is probably the finest blue threadlocker you can buy, not just for model making, but also if you're an avid home mechanic !

It seals metal parts to prevent them vibrating loose, but allows them to be easily removed when required using hand tools. The manufacturers describe the formula as "agressive" because no primer is required, you just need to ensure the parts are clean and free of oil or grease prior to assembly.

Although the parts are ready to use immediately on assembly, maximum strength develops in 24 hours. As with all such products, don't get it in your eyes or drink it !

This item is a 6ml (0.20 fl oz) bottle.
