Must use the whole tube when opened or it dries out
Works as it shoukd so far but the fact i onky ised about 5% of the tube for one job and the rest of the tube is now useless as it has dried up with every precaution taken to avoid this the cakue for money is very poor.

Good Product
I used Sikaflex on my campervan to add additional sealant/adhesive to the mud flaps. Excellent results. Only problem is if you don't use it all it does go 'off' rather quickly even if you try to seal the top.
