1. Gorilla Patch & Seal Liquid Rubber Waterproof Sealant, Crystal Clear, 32 Ounce (Pack of 1) – Seals Out Water, Air, and Moisture
This earns the top spot because it solves the biggest visual eyesore of DIY repairs: unsightly, thick colored globs. It provides a transparent finish that blends into surfaces, making it my clear favorite for repairs where appearance matters as much as the seal.
The coverage area is impressive, acting like a liquid shield that blankets large surface gaps. I think this is the most versatile choice for anyone wanting a professional look without the mess of black or gray products.
Buyers frequently praise its ability to stay clear even after curing.
The 32-ounce container provides excellent value for large-scale outdoor projects.
Users often report that it settles into tight crevices without needing manual smoothing.

2. Gorilla Waterproof Patch & Seal Rubberized Sealant Paste, 12.8 oz Can
If you are the type of person who needs to bridge a significant gap, this paste is your best friend. It has a thick consistency that stays where you put it, acting like a structural filler rather than a simple coating.
I find this product ideal for deep cracks in brick or concrete where liquid sealants would simply drain away. It feels like putty in your hands, giving you full control over how you fill and patch problem areas.
Users appreciate that it does not drip or run during application.
It is widely considered the best option for filling wide, uneven holes.
Many buyers suggest using a putty knife for the cleanest, most uniform results.

3. Gorilla 84756 Waterproof Coat & Seal Black 473ml
A surprising feature of this sealant is its incredible tolerance for extreme weathering, which makes it a workhorse for heavy-duty sealing. It forms a coating that feels almost like a rubber tire, ensuring that water has zero chance of penetration.
I would suggest this for roofs, gutters, or hidden exterior areas where the black finish remains out of sight. It is a rugged solution for anyone prioritizing sheer performance over aesthetics.
Customers note it remains flexible even in freezing temperatures.
The black finish is highly resistant to sun-driven color fading.
It is the preferred choice for sealing industrial-grade joints.

4. Gorilla Waterproofing Spray, Black, 16 oz, 2-Pack, Flexible Sealant
While buyers often complain that the spray nozzle can clog if not cleared immediately, the speed of application remains its strongest selling point. It is a time-saving tool for covering wide, flat surfaces where precision is less important than total coverage.
I view this as a convenient option for those who dislike the manual labor of brushing or troweling. It functions like a protective mist, creating a thin, water-resistant barrier on almost any material.
Users recommend keeping the nozzle clean after every use to prevent blockages.
It is best suited for light-duty sealing and preventative maintenance.
The fast-drying nature makes it useful for quick emergency repairs.

5. Gorilla 100% Silicone Caulk, Waterproof Sealant, 2.8oz Squeeze Tube, Clear
When you compare this to the spray above, it becomes obvious that this is meant for finer, more surgical tasks. It lacks the spray's broad reach, but it offers surgical precision for indoor bathroom or kitchen fixtures.
I would point you toward this option if you are resealing a sink or shower edge. It is a standard household staple that performs exactly as expected for small, localized leaks.
Many buyers prefer it for its mold and mildew resistance.
The small squeeze tube is perfect for storage in tight kitchen drawers.
It provides a more permanent, rigid bond than the liquid rubber alternatives.

Choosing Between Them
I recommend the Crystal Clear Liquid for most homeowners because it offers the most versatile finish for visible repairs. If you need heavy-duty filling, reach for the Rubberized Paste, while those tackling bathroom fixtures should stick to the Silicone Caulk. The Black Coat & Seal remains my top recommendation for hidden, high-stress exterior areas where performance is the only priority.
Regardless of which version you choose, you should always remember that these chemical sealants require proper ventilation and patience during the curing process. Always allow for adequate drying time to ensure a long-lasting bond that stands up to the elements.
