Where these two actually differ
- Neither product has a hazard flagged against it, which is uncommon and is why both grade as well as they do.
- The Kiwi is Proprietary durable water repellent (DWR) treatment on fabric and leather where the Scotchgard is Proprietary liquid spray coating (composition unspecified), which is most of the difference in these two grades.
- These two are 5 points apart, close enough that price and fit should decide it rather than our grade.
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 →
