#WalnutOil is not necessary.
I use walnut oil as I've had it around (this bottle almost 10ys). Any oil with high #unsaturated fatty acid content works. The unsaturations (double bonds) are what react & polymerize. So flaxseed, sesame or castor oil (bacon fat ok too; it's high in monounsaturated fat).
