Review: Good stuff - This stuff works great for ceiling pipe threads. I like to put this on my threads and then a little bit of Teflon tape over top of it or vice versa. Definitely worth the money. Great seal, easy to use, and easily removed with a towel.
Review: If it has threads this it!! - I've been using laco for 50 years of my life in the plumbing and gas fitting trade. High end restaurants,it seals the threads and has lubricant abilities which allows the fitting to tighten even better. Best part is years later when undoing fittings they come right apart. If I could give it 10 stars I would. Retired 4 years ago and yep got a bottle in my tool bag. Very easy to use and any excess wipes right off...
