Worked in the outer Hebrides under a gale force storm sealing a leaky motorhome roof whilst pouring down - sealent sticky and doesn’t wash away or harden .

Great
Bought this as a last resort as tried usual stuff and even vinegar/soda etc , showed trap is thy ear modern ones that block often , poured this down into shower trap bucket and let fall over edge ( half a bottle ) , left 24 hours and tried thinking the worst - was over the moon it must have shifted whatever the blockage was as shower water running away lovely .
Top Product - not more expensive than usual supermarket rubbish but it is very effective .
