A fast curing, polyurethane-based, flexible adhesive sealant which is ideal for general sealing applications above and below the waterline, although it must be initially applied to a dry surface. Sikaflex is salt water resistant and can be used to seal joints including keel/hull, stern shaft tube, bonding deck to hull and more. Other marine applications include leaks, deck fittings, hatches and bedding wooden decks to metal, wood or gelcoat. The non-corrosive formula is odourless, weather resistant and does not conduct electricity. Will be touch dry in just 45 minutes and can be sanded over or painted four days later. Also available in 70ml.

I used this to refix the rubber surround on my windscreen. I'd tried normal silicon and another type of glue and both had failed on the motorway resulting in the rubber being detached. I've driven over a 1000 miles and it's still in place. It's not what it was designed for, but it works perfectly for this application.
