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.

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...

Great except for the strong smell
Really worked very well. You have to put this on both the pipe and the fitting to make sure it gets into the threads. The only problem is the smell, it lasts for days to weeks. I used this on a steam pipe and the smell(which can burn the eyes) is now almost gone after 2 weeks. Use in very well ventilated place or during the warm weather so you can keep the window open. I would recommend this product.

SUCCESSFULLY STOPPED an oil leak where the "name brands" failed!
THIS STUFF IS THE BOMB! Stopped an engine oil pressure sensor leak that the "name brands" failed to seal!!!! No need for long cure times either; just apply to threads, torque it down, and your good to go!! THIS IS NOW MY GO-TO THREAD SEALER!!

Came up short
This is a great product. However the bottle I received came up a quarter light. Maybe because the lid does not close. Maybe for other reasons we do not mention here.

The last resort should have been my FIRST!
Like many on here, I had a plumbing fitting that would not seal well and not matter how much tape or tightening I did, it didn't stop with the micro leak. One application of this was all it took and I had no worries to start hanging drywall. Would recommend.

High quality pipe dope, smooth threading. Personally, I first tape, then dope with this. If you want to take joints apart at some point, this is it.
