Soft99 Corporation is a Osaka-based car care manufacturer founded in 1954, best known in the West for its Glaco family of hydrophobic glass coatings and for Fusso-technology wax products. The brand is a dominant force in the Japanese domestic market and has expanded steadily into Europe and North America through authorized distributors.
The Glaco product line spans from basic IPA-carrier roll-on repellents to longer-lasting Fusso-bonded glass coatings (Ultra Glaco) and dedicated glass cleaner/prep products. Soft99 holds a strong reputation among Japanese-car enthusiasts for chemistry rigor and clear product differentiation across durability tiers — a deliberate contrast to the single-product approach of Rain-X.
