Hi Folks, previous owner of my 1991 Cooper has put a Canvas style roof over the normal metal one.Have been over it with a magnet from a radar(quite powerful, Dad was in RAF and must have borrowed it,it's only been 30 odd years

). Doesn't seem to hiding anything and is starting to fray and a bit missing, looks pants. Have had following advice:
a: Use a Hot Air gun
b: Slit the roof and pour in Thinners?
Has anyone removed a roof like this?
Is there a Link to disassembling the 3 pod Binnacle, have looked and only found destructions for 2 pod, as want to make my own Dash(thanks to Caerdydd mini Club for the template),
Thanks for your help,
G
