Detailed Review

Liquid Rubber MetalSafe Sealant is a premium rubber-based coating designed for protecting metal surfaces like roofs, sheds, gutters, and more. It suits homeowners, contractors, and DIY enthusiasts dealing with corrosion, leaks, or weathering on metal structures, offering a professional-grade waterproof membrane that bonds directly to lightly rusted areas without extensive prep.

Standout features include ultrahigh corrosion resistance, UV stability, and solar resistance, creating a seamless, flexible barrier up to 80 mils thick on flat surfaces. Real-world users report it excels at sealing leaks on Quonset huts and metal roofs, filling pinholes and screw holes while providing surprising coverage, often using less product than expected. Reviewers praise its thickness for truck beds and tool handles, confirming strong adhesion and weatherproofing through heavy storms.

The liquid form applies effortlessly with a brush, roller, or heavy-duty sprayer, drying fast with a color shift from brown to black for easy oversight of coverage. Build quality shines in its rubber-like durability, making surfaces easier to walk on and more resilient than standard paint.

Drawbacks include messiness during use and the need for multiple coats in ideal conditions above 50F, avoiding hot sun or dew. Coverage demands generous application for best results.

Overall, this sealant earns high marks for performance and ease, making it a smart choice for reliable metal protection and leak repair. Highly recommended for anyone needing tough, long-term waterproofing.

Buyer Guide

Prep surfaces by cleaning and removing loose rust or paint. Apply 2-3 heavy coats on vertical surfaces (1 gal/30 sq ft) or 4-5 on flat areas (1 gal/15 sq ft) above 50F. Use brush or roller for best control; sprayer for large areas. Ideal for metal roofs with leaks or corrosion.

Avoid application in direct sun, heat, or before dew. Test small area first on rusted spots. One 5-gallon pail covers substantial areas like a 10ft Quonset hut end with coats to spare.
