SEM Plastic & Leather Prep - 12oz

The SEM Plastic & Leather Prep is a professional-grade solvent blend designed for technicians and detailers who require flawless adhesion on trim pieces, dashboards, door panels, and leather surfaces. This 12oz aerosol formula effectively removes contaminants, waxes, oils, and residues that can compromise bond strength before applying adhesives, dyes, or protective coatings.

The chemistry behind SEM Plastic & Leather Prep works by dissolving factory release agents and manufacturing oils that are applied to prevent sticking during production. Its solvent composition is strong enough to break down stubborn residues without damaging soft-touch plastics, genuine leather, or vinyl, which is a common issue with cheaper alternatives. The aerosol delivery system ensures even coverage across irregular surfaces, dashboards, and seams.

Professional collision centers, upholstery shops, and serious DIY restorers rely on this prep solution before installing replacement door panels or applying leather dye. By creating a microscopically clean substrate, it allows adhesives and coatings to achieve maximum mechanical bond and visual clarity without hazing or adhesion failure.
