A customer has dropped in a steering wheel to be retrimmed, but the foam is totally gone. Normally I start with wheels that have good foam with only minor repairs needed, but this foam has completely turned to dust.
The steering wheel has sentimental value, so it has to be this wheel rather than finding a better one.

I've searched for round section high density foam but can't find anything. Does such a thing exist or am I going to have to cut and shape it from high density sheet? It's a fairly basic design, no indents or sculpted shapes, just round foam.

Any advice or sources for foam would be great! I'm UK based but don't mind importing the right product, there's so much more choice in the US.
