Surfacing wax additive

[insanity]

I had a quart of wax additive, haven't used it in awhile and part of if seemed to have evaporated. I added some styrene to break up the parrafin and shook it up good, seems like its back to normal.

Any issue to be had from this? What is the usual 'solvent' in the surfacing wax? It was the Surfacing Wax (Mod-C) from US composites.
