Future sort of turned into Pledge Floor Care under a couple of different names made by Johnson, then that too went off the market as well. The rumor is Quick Shine is a product that behaves very similarly. I've never tried it so maybe someone else here has.
Being a floor cover, Future is very durable and will not yellow. Yet at the same time, it is very gentle to model plastic. I am surprised that not enough test were done by modelers to come up with an recommendation.
