Metallic FAQs Prev Page 1 of 1 Next 1. Can I top coat Metallic? We do not recommend top coating our Metallic spray paint. These are made with real metal leafing flakes and a top coat will dull the sheen. 2. Are these for Indoor/Outdoor use? Our Metallic spray paint is for indoor use only. Without the use of a topcoat your project will not be protected for the outdoor elements. 3. Do I need to prime before painting my project? Using a primer will help provide superior adhesion and hiding. We recommend priming especially for bare wood and metal. Prev Page 1 of 1 Next
