Durably elastic and waterproof coating for seams and damaged material.
Seam grip can repair tears and holes in rucksacks, tents, clothing, tarps, footwear, air mattresses, lather and foil - even in parts where up to 3 cm² of stuff are missing!
It remains elastic, does not dry out or become porous.
By the way - opened tubes can be deep frozen and used again later.
