X means there is no data available to specify a protection rating with regard to this criterion. In the 1st posistion it means particles. There is no protection on coated models. The original Aura HD H2O was externally sealed, so was protected.
8 in 2nd position means

The equipment is suitable for continuous immersion in water under conditions which shall be specified by the manufacturer. However, with certain types of equipment, it can mean that water can enter but only in such a manner that it produces no harmful effects. The test depth and duration is expected to be greater than the requirements for IPx7, and other environmental effects may be added, such as temperature cycling before immersion.

Fresh Water, not chemicals or solvents, unless the manufacture details otherwise.
Basically the "waterproof" or proforma coating method is cheap compared to a true waterproof enclosure and dates from before 1940s, though the materials are different. Unlike a waterproof enclosure it doesn't protect connections. Sealing may fail on switches and on PCB at connector. It may have pin-hole defects.
Resistance to various fuels, solvents and chemicals depends on age and the coating, usually a polymer.
Exorbitant marketing claims are made by the makers of the coatings, often using gratuitous use of the word nano.
