Stoner

Stoner is a specialty chemical company that makes a focused lineup of automotive products well. Tarminator (tar and adhesive remover) and Invisible Glass (glass cleaner) are their best-known products — both are category leaders that enthusiasts and professionals reach for by name. More recently the brand has moved into ceramic chemistry with Trim Shine Ceramic, a polysilazane coating kit for plastic and vinyl trim.

The company has deep formulation expertise in both solvent and ceramic chemistry. No-frills brand that competes on performance rather than marketing.
