Review: Lasting fix! - I recently used Rust-Oleum 265495 LeakSeal Flexible Rubber Coating Spray in Clear, and I'm quite satisfied with its performance. Here's my review of this product: 1. **Effective Leak Sealing**: The primary purpose of this product is to seal leaks, and it does this job impressively. I used it to seal a leak on a gutter, and it formed a flexible, rubber-like barrier that effectively stopped the water from leaking through. 2. **Clear and Discreet**: The fact that it dries clear is a significant advantage. It maintains the original appearance of the surface you're sealing, making it almost invisible. This is especially valuable for applications where aesthetics matter. 3. **Ease of Application**: Applying this spray is straightforward. The can design allows for precise spraying, ensuring that you can target the specific area you need to seal without overspray. 4. **Quick Drying**: The product dries relatively quickly, which is convenient when you want to complete a repair or sealing job promptly. 5. **Flexibility and Durability**: The rubber coating is flexible, which is crucial for accommodating surface movement without cracking or peeling. It's also durable and can withstand exposure to various weather conditions. 6. **Versatile Use**: While I used it for gutter repair, this product has a wide range of applications. It can be used on roofs, pipes, windows, and more. Its versatility makes it a valuable addition to any DIY toolkit. 7. **Long-Lasting Results**: Over time, the sealed area has remained leak-free, which demonstrates the long-lasting effectiveness of this product. In conclusion, Rust-Oleum 265495 LeakSeal Flexible Rubber Coating Spray in Clear is a reliable solution for sealing leaks and protecting surfaces. Its clear finish, ease of application, and durable, flexible coating make it a valuable product for various projects.

It's a handy tool for homeowners and DIY enthusiasts looking for a quick and long-lasting fix.
Review: Works Great! - As usual, the desertcart.com delivery was faster than the dates stated. Thank you very much! The Rust-Olem spray works really well for the intended purpose. I used it to stop leaks in my rain gutter where the parts fit together. The main concern: make sure you know where you are aiming the spray and understand the spray is wide right out of the can. The instructions say to hold the can 8-18 inches away from the location you want to stop leaking. (I can't imagine a leak this product could stop if you needed to hold the can 18 inches away to cover the area. You would probably be more successful calling a plumber.) If the leak is a small area, as in a gutter leak, I would recommend holding the can more like 3-4 inches from the spot to be sprayed. Otherwise, you may be spraying your house or something else you did not intend to get the black tarry spray on. Clean up can be difficult and stressful. Use short, quick sprays for the best results. Using a good size piece of cardboard as a back drop between the gutter and the house is a good idea (a lot less clean up and a whole lot less stress). Just trash the cardboard when you are done. And, do not forget to hold the can upside down, to clean out the nozzle, when you are finished. This only takes about 2-3 seconds of pressing in on the spray button.

## Questions & Answers

**Q: How long is the drying time.sprayed the fish pond ( second time)when can I safely put the fish back into the pond?**
A: It all depends on how thickly you applied it but 24 hours should do it.

**Q: Someone complained that it came out in a stream, I need it to spray, to use on roof, does it spray? And how much coverage? And how warm does it need to be, if I take it from inside(warm) to outside(cold roof) ????**
A: Like many of these kinds of products, you shake it first.  The stream is fairly narrow - the kind you need to run along a seam or some similar application (not a fine spray like a window cleaner).  Personally I like the Flex Seal a bit better as it applies a bit for thickly than the Rust-Oleum.  Can remember the exact temp requirements but something above 50 degrees F. as I recall.  One 11 oz can will do maybe 30 to 40 feet of metal seam, window trim, or related apps.  Possibly a bit more if you move along quickly.I thought I'd add the note that for wider area applications (I've had leaking metal roof issues) you might want to try "Thru-the-Roof" which comes both in tubes and quart/one gallon cans.  Then the liquid is applied by paint brush from the cans.  This works best for large areas.

**Q: Can this product be used to waterproof a tile/grout shower?**
A: Yes. Have an upstairs 30" x 30" tile shower with fiberglass pan that started leaking (not from drain but from somewhere up the walls.)  Could see leak from downstairs ceiling (opened up ceiling to find leak source and repair ceiling damage).  No obvious cracks in tile grout or in the caulking where the tiles met the pan.  The tile job is old and not high quality (previous owner).  Sprayed a few thin coats of the clear sealant and the leak reduced.  Ended up using two cans on walls in multiple coats to eliminate leak.  Suggest washing/scrubbing walls with distilled vinegar and rinsing well before spraying to remove soap buildup so sealant will adhere to tile/grout better.  Sealant went on like spray paint (did not experience any globs as noted in other comment).  Keep the can moving before and after you press the nozzle to avoid uneven saturation.  Cannot really see final coating over tile after drying.  Maybe not suited for a high-gloss, fancy tile job but great for a standard bath tile where you are hoping to get more years of utility before a remodel.

**Q: NOTHING will stick to my tub, even caulked by plumbers.  Would this work??  I don't care what it looks like!**
A: I am not sure about the glazed finish of a tub might not hold. Have used it on other smoothe finishes though and it has held.

### ⭐⭐⭐⭐ Good Product. Works on Old Metal Roof
*by R***R on April 2, 2013*

I have an ancient farm house with an old rusting steel roof over the front porch. It has some tiny pinhole rust leaks which I wanted to remedy from the bottom side, because traditional coatings on the top side would ruin the old-roof patina and look. Got this idea when an info-mercial came on about essentially the same product. The pitch man replaces the bottom of his boat with a screen door sprayed with the stuff and motors off on a lake. You know the pitch, buy this amazing product now and get two for only (unspecified) additional handling charges. So I googled the product for reviews and learned that it does work, but is the same thing that is available in stores from Rust-Oleum and others. Worked very well. Has low viscosity when first sprayed, so it will run and drip if you are not careful in applying it to an overhead surface. I've had one hard rain since using it and it did the job. As always, delivery and service from Amazon was superb.
