i've bought a laddermat,
which was mentioned on this group a while ago,
it has rubbery spikes up and down,
and is adjustable for slopes,
seems much safer and a good buy...

Can replacement buffers be obtained from the ladder manufacturers?

Currently they are riveted in place, but I guess that nuts & bolts
would work just as well if I have to drill the rivets out.
I wrap towelling round the top when resting on paintwork etc.

That's what old socks are for!
