Ok you are comparing two different products. It's an apples to oranges comparison.

One is a spray wax that leaves protection in D156.

The other is a detail spray that leaves no protection behind but can be used to remove light dust, finger prints and can be used as a clay lube.

So if you want to leave a durable form of protection then use D156. If not then use D155. Again it is all up to the user. You can use either one as much as you like.
