PS10 Yellow Wax vs Race Run Spray On Wax: which is safer?
Swix PS10 Yellow Wax is the clear pick. Dakine Race Run Spray On Wax carries a failing PFAS grade, and we never recommend buying a failing product.

Where these two actually differ
- We flag Combustion by-products during hot application, Skin and eye contact irritation, Ingestion toxicity (accidental exposure) and Microabrasive particulates from worn base or scraping on the Swix and not on the Dakine.
- We flag Solvent and propellant inhalation (VOC exposure), Undisclosed water-repellent chemistry (possible PFAS or alternatives), Microparticle or aerosol deposition on skin and respiratory tract and Allergen or sensitization potential from undisclosed additives on the Dakine and not on the Swix.
- The Swix is Hydrocarbon-based ski wax (paraffin/synthetic blend) where the Dakine is Spray-on wax coating, formulation undisclosed, which is most of the difference in these two grades.
- The gap is 60 points, wide enough that this is not a close call, and the Swix is the one to buy.
- We are less certain about the Dakine grade, at 35% confidence against 72%, because it discloses less.
Both products run through the same public rubric: materials, coatings, brand disclosure, lab findings, and recalls, plus a beyond-PFAS hazard analysis. Grades are model-based estimates, not lab tests. How grades work →
