I think the liquid steel is a KBS product? Haven't had much luck locating it here in Perth, (although I haven't looked that hard). I'll put these aside for spares, and to trial the method you've listed, (in the long term). I do have new non blue box ones to go on the car.
I've had to resort to blue box parts for a couple of pieces as there was nothing else available, but they're more cosmetic parts, other than rotating, sealing, or machined parts.
Cheers,
