Review for Fernox LS-X External Leak Sealer 50ml
Replies for Fernox LS-X External Leak Sealer 50ml
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.
