Review: Worth the money. - If you have pvc pipe then you know that it moves and that you have to seal it and that the blue glue is the best to seal it as it is water proof but not so solid that you can't cut it with a blade if you need to. It is easy to use, low order, works great, light mess, mix it up and it will thin out you do not want big clumps. thin coat around the pvc pipe. dries with in a few minutes.
Review: Plumber Recommended - Used for sealing my shower heads, in combination with plumbers tape. It was very easy to apply, and the brush was quite helpful. The sealant itself is of high quality. It's quite sticky, so try not to get it on your fingers, or you'll need warm water to remove it.
