Ah, a good point, it's slightly curved.


The curve isn't a problem, except it will throw all your measurements
out when you cut the new material.

How do you propose to cut the new hardboard to fit exactly? Surely, a
spot of filler and some paint is going to be a small fraction of the work?

Where you have joins in the white coated hardboard, how are these
covered at present?
