The shelf paper might be something like what some of the Chinese ARFs have on them. That stuff works ok.

If you have an accurate scale, if you'd be so kind as to measure out a piece and weigh it it'd surely be of value to know what it's oz/sq ft is. That way, we'd all benefit knowing where the best places to use it would be. If it's light enough, it could also work on the tail surfaces and being cheaper than monokote would be even better to use for most.
