Ohhh
Not that's a turn about. Usually I'm looking for a non-marine product for a
marine use !

No, actually I need the stuff for a completely non-marine related
application (backing for Sixties-style guitar straps - trying to make them
as authentic as possible & 1/8" vinyl is what they used back in the day.)

Here is an example: http://www.axestraps.com
But I was told that that type of vinyl was used for marine purposes so
thought I'd ask here! :-)
