Epoxy Primer is the best choice for bare metal or plastic because it delivers maximum adhesion, corrosion resistance, and a strong foundation. High-Build Primer is ideal when you need to fill scratches, sanding marks, or minor imperfections before paint. In short: use Epoxy for sealing and bonding, and High-Build for leveling and surface correction.
