Which Zinsser paint is best?

Which Zinsser paint is best? Which Zinsser paint is best depends on application. For exterior multi-surface where you need primer and topcoat in one that adheres to wood, metal, masonry, plastic, and previously painted surfaces, Zinsser AllCoat Exterior is considered best, available in satin, gloss, and matt, with good weather resistance and flexibility. For interior multi-surface, Zinsser AllCoat Interior is best for similar versatility. For bathrooms, kitchens, and humid areas prone to mold, Zinsser Perma-White is best, as it is mold-resistant paint with durable finish that prevents mold growth on paint film for years, available in matt, satin, and gloss. For specialty, Zinsser AllCoat is often rated top for upcycling and exterior furniture. If you mean primer, best is B-I-N shellac for heavy stains and odors, Bulls Eye 1-2-3 for all-purpose, and Cover Stain for oil-based heavy stains. So best paint is AllCoat for general multi-surface exterior and interior, and Perma-White for mold-prone interiors. Choose based on whether you need exterior durability, interior versatility, or mold resistance.
