Silver Grey , high frequency welded vinyl in 2" strips along the width of the roll, which is 137cms.  Use for cockpit upholstery, matches with the Silver Grey Vinyl.  Use this for the tops of your cockpit cushions and use the matching plain vinyl for the underside and sides of your cushions.

I dont have an image of the silver grey fluted, but its exactly the same as the sample of plain vinyl, but welded.  The cost to send out this material is £26.50 by DX
