How 'workable' is it when solid? Easy Can it be cut, filed, sanded, drilled, etc. with ease? Yes
How strong is it when solid? IMO, not bad Is it as hard as a piece of ABS of the same dimensions or is it more plastic? IMO, Yes, maybe not as rigid tho
Keep in mind, if left in direct hot summer sun, it may distort, however, at room temps it retains it's shape.
