ASPA provides a unified industry voice for its members engaged in the automotive chemical and vehicle appearance product markets before state, regional and federal legislators and regulators. ASPA draws upon the combined services offered to companies in the automotive chemical and vehicle appearance product markets through the Motor & Equipment Manufacturers Association (MEMA), the Auto Care Association, and Household and Commercial Products Association (HCPA). Membership in one or more of the three sponsoring associations is required for a company to participate in ASPA.
