Optimum Protectant Plus - Shelf life

[TRex99]

Found a gallon jug of OPP about a third left in it stashed behind some stuff on a shelf. I bought it a long time ago, and I guess I forgot about it or thought I ran out because I haven’t used it in quite some time (been using Cockpit Premium for awhile now).

Anyway, this stuff has got to be at least five to seven years old. Still safe/effective to use? It emulsifies up fine when shaken and seems to look OK.

Probably fine... possibly less durability but only time will tell.
