    I've been using Tru Blu by Rectorseal without problems,also its available at my local wholesalers. I've not been impressed with Leak lok though, i only use it on level sensors on milk tank wash systems as its what was used in the factory.

    I might get a tube of loctite 577 and compare it to Tru Blu as trying new stuff stops me getting bored.
