Car-Rep Adhesion Promoter is a clear, single-component (1K) aerosol sprayed on before primer or paint to create a surface the following coats can actually grip. The manufacturer describes it as preventing lifting, solvent attack, and chemical reactions between coats, and it's compatible with both solvent-based and waterborne primers and topcoats.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003e\u003cstrong\u003eFast-drying, simple application\u003c\/strong\u003e \u003cem\u003e(H2)\u003c\/em\u003e\u003cbr\u003eIt's a straightforward aerosol: no mixing, no activation. It dries quickly and is designed to be topcoated soon after application — sources put the window at roughly 5 to 10 minutes after the final coat, so check your can's label for the exact figure before starting.
