How to Seal Your Windows With Flex Shot

Seal Outdoor Elements With Flex Shot!


No more window leaks. Grab your can of Flex Shot and seal your windows with no hassle. RV skylights? Car windshields? Home windows? Flex Shot does it all. It dries into a thick, rubber, adhesive sealant protecting almost any surface. It’s like your “rubber in a can” – blocking out water, moisture, and air.


Supply List:

● Flex Shot
● Painter’s Tape
● Drop Cloth
● Sharp, High-Quality Scissors
● Mineral Spirits


DIY Project #1: RV Skylights.

Inspect the skylight from your roof to see exactly where the leak is coming from. Scrape away any old sealant and make sure your surface is clean. It might take some elbow grease to remove the old sealant. Rub away any residue with mineral spirits and a rag. Once dry, cut the extension tube of your Flex Shot with scissors. This will help you control the size of your bead. From a 45 degree angle, press the nozzle completely around the seam where the RV’s roof meets the metal or plastic flangers of the skylight. Don’t leave any gaps in this area – or your RV will be susceptible to more leaks.

[Flex Tip: Flex Shot can withstand extreme temperatures. So you don’t have to worry about it dripping, cracking, or sagging in the cold or hot seasons. Flex Shot works best in conditions ranging from -76°F to 350°F.]

DIY Project #2: Car Windshield.

Remove the weather rubber strips from your windshield. For some, that might require unscrewing them. Completely clean and dry your entire windshield, making sure the area is free of dirt, oil, and debris. While Flex Shot comes in four different colors (white, almond, clear, and black), Flex Shot Clear is probably best for this project. It works like an invisible glue. Press the nozzle and caulk the outline of the windshield. If you get Flex Shot Clear in any unwanted areas, just wipe it away with a paper towel. Let the caulk dry for 48 to 72 hours before reapplying the weather rubber strips back to the windshield.

[Flex Tip: Before caulking your home windows, remove any old caulk. You can scrape it off with a razor, or you can buy a caulk removal tool from your nearby home improvement store. Make sure that the surface is dry and clean of dirt, grease, or oil.]

DIY Project #3: Home Windows.

Flex Shot can be used to caulk your home windows from the inside and outside. Cut the extension tube with sharp, high-quality scissors. Now that you have a clean surface, from a 45 degree angle, press the nozzle into the joint or seam where the window and wall meet. Flex Shot will come out in a perfect bead. Make sure you don’t miss any areas. Caulk around your entire window to make sure no air, moisture, or water can seep through. After caulking your window, run your index finger along the caulk to make sure it fills every crack along the window. Grab a paper towel to to wipe away any extra caulk as quickly as possible (within 20 minutes from applying). Use this for both inside and outside of the windows.

[Flex Tip: You can use Flex Shot over and over again. When using standard caulk, any leftovers will harden and end up getting trashed (a complete waste). But with Flex Shot, just leave a small bead (approximately 1/8”) sticking out of the top of the nozzle. When you’re ready to reuse the can, pull out the bead of dried product and use Flex Shot again.]
