RS Motorsport :: Classic Speed Restored

Does anyone know of an equivalent modern product that is similar to what ford used around the floor (in particular to seal the rubber bungs).
The stuff I am describing is like Sikaflex (flexible panel adhesive) but remains softer, almost like it doesn't skin and cure.

I want to put my rubber bungs back in a want to seal with something similar.

Thanks

I use a Wurth sealer - comes in a tube but its called "Spray Sealer"
From the label "Suitable for: Sealing seams when replacing panels in the engine compartment, boot, floor pan, suspension strut etc" It's grey. I put it on with a gun and then use a paint brush to spread it and you get a very good factory look and its flexible. Good stuff
