Ready Seal, an oil-based, semi-transparent sealer and stain for wood, comes with a “goof proof guarantee.” According to the manufacturer, it won’t run or show lap marks during application; doesn’t need back-brushing when applied with a sprayer; and doesn’t need sanding or stripping before reapplication. The stain also is guaranteed not to flake, chip, or peel. Ready Seal is available in seven colors and contains less than 100 grams of volatile organic compounds (VOCs) per liter, allowing the stain to be used in all 50 states. It’s available online and at some Home Depot locations; it costs $39 a gallon or $169 for a five-gallon container. Ready Seal, 888.782.4648,
