Worn cylinder barrels

Has anyone had any recommendations for replating the cylinder bores? I’ve found this company:

They advertise Nikasil coating but are there others about?

I think theres somebody in Weston Super Mare…the name escapes me…Google ?

Will have a look.
Thanks

The company is Langcourt. They have some good reviews on various classic web sites. Very helpful, and sensible prices when I rang.
