Sika 521 UV Hybrid Adhesive Sealant - Black

Mutts nuts

BEST 'mastic' type of gunk I've used.
Sticks, is actually waterproof and sets like rubber so can be tooled into shapes before setting to form an effective seal.
Doesn't go off in the nozzle so you don't have to worry about wasting either the nozzle or whole whole tube.
Is genuine marine grade & UV stable unlike all the rubbish it is replacing on my bus conversion.Read full review

Excellent

Has done an amazing job round all the roof windows and bars on my Disco TD5 2. Now have a lovely dried out vehicle. Time will tell if it needs renewing or topping up, but so far it has cured beautifully and feels just like sound window rubber. Read full review

Have not found anything superior for sealing polycarbonate sheet to Aluminium

Highly UV resistant ,so absolutely ideal for outside use in direct sunlight and has proved to have a sticking power strength greater than materials being joined when left for over 12 hours to cure.
