I have used this in the past and only last about 1 year before it starts to peel off and wear down and needs redoing. Ended up finding an insert that you glue into the groove in the decking, they looked very smart and have been fitted now for a few years and look like new. Can't remember who I got them from but it seems a company called Gripdeck manufacture them https://www.gripdeck.co.uk/retrogrip/
