I have found oil-tempered hardboard to be an excellent topping for workbenches. The product is harder and smoother than standard hardboard and more resistant to staining from oil and paint spills.
My impression is that it is less readily available today than some decades ago but someone did point out that it can still be had from large stockists.
I didn't know that the oil concerned was linseed or, indeed, that it was baked – thanks, Neil.
