Wow steady there Stu, that's almost good advise !!! Spose your "leather" is yellow LOLIs it leather or vynal,
If it's vynal a heat gun used carefully will remove most, if not all of it,
If you've never used a heat gun, stay away from it, fires cost loads to put right,
If it leather try a trimmer to see if it can be repaired or treated,
Hope this help, feeling your sorry,
Goldie
