Which future floor gloss am i supposed to use?

Future is now called Pledge. Future had a blue and white label. Pledge has a brown and yellow label. Both are the same product. If you find a bottle labeled Future, it's old stock, but should still be good.

I use Pledge multi surface polish - 

berd

a white and blue bottle verison

- yep, that sounds like the stuff.

I found the yellow brown version, will this work?

Here's a link showing what the product is from the FSM How To section on this site.

Future works great but so does any other high gloss finish so there's no need to search for the stuff. The only advantage I've ever found is that it makes clear parts more clear and offers some protection for them from glues and solvents.
