As others have said it's a must have for the toolbox. Has got me out of a few sticky situations. Not cheap but definitely the best.

One of them things you just having your tool bag - I would recommend wearing gloves when using it as it’s not the easiest to get off your fingers

This is great for using on olives to stop slight weeps. Also great to stop weeps on other stuff too. Always carry some in my bag. Always sets near the cap but not a problem.

If you need to seal a little weep on a fitting or boiler part till you can replace it works a treat and you can apply it wet and it sets up in 30 minutes.
