Neil I will have to leave this part to you as I know very little about closed cell foam . Maybe a trimmer can give you a bit of advice .
I could take the pee by saying closed cell !! OZZY but I can'nt think one up too tired.Been out in the mog all that fresh air and I nodded off watching only fools and horses must be zonked to miss that.
[quote=Jack The Lad]They are good but remember there is no give in a solid surface as in the horse hair so if the leather is rubbed against it will scuff
Good point, JTL.
How about a layer of closed- cell foam to cushion it? Am I right in thinking that should not absorb any moisture?
