I can read the can it says "Glassodur Urithane Acrylic "in black, and a large "21" on the can, and maybe Glasurit in blue print at the top but it is obsceured by paint runs and old masking tape. The company or line may have changed. I figure this can may be up to seventeen years old.
I did a search and found under "Glasurit" just what you mentioned .They show two lines .A "22" which is a single stage Urithane and 1"55" which is a basecoat clear piant.
