Weather Defense Wood Protector 10 Oz. vs Waterproofing Wax for Leather: which is safer?

Where these two actually differ

• We flag Volatile organic compounds (VOCs) and solvent inhalation, Respiratory and dermal irritation from unknowns, Coating failure and environmental persistence and Mildewcide or biocide residues (if present) on the Guardsman and not on the Nikwax.
• We flag Respiratory irritation or fume inhalation during application and PFAS in water repellency treatment on the Nikwax and not on the Guardsman.
• The Guardsman is wood protector/sealant coating (composition unspecified) where the Nikwax is wax-based waterproofing, which is most of the difference in these two grades.
• The gap is 25 points, wide enough that this is not a close call, and the Nikwax is the one to buy.
• We are less certain about the Guardsman grade, at 35% confidence against 78%, because it discloses less.
