Brushable Seam Sealer - evil snotty sh!t

[CycloneMike]

The tubes are sealed to stop it setting. You will need to stab a hole in the nozzle end. At the bottom you will need to stab it again with a screw driver or similar and then peel out the metal disc. Works like a ring pull food tin but with no ring pull.

I like this stuff as it has built in spreader or squirt it out and brush etc
