My Buying Guides on 303 High Tech Fabric Guard
When I first started looking for a reliable fabric protector, I came across the 303 High Tech Fabric Guard. After using it myself, I wanted to share what I learned to help you decide if it’s right for your needs. Here’s my detailed guide based on my experience.
What Is 303 High Tech Fabric Guard?
303 High Tech Fabric Guard is a spray-on protector designed to restore and maintain the water and stain repellency of outdoor fabrics. I found it especially useful for gear like backpacks, tents, boat covers, and outdoor furniture cushions that had lost their original protective finish.
Why I Chose 303 High Tech Fabric Guard
What caught my attention was its ability to renew the durable water repellent (DWR) finish without altering the fabric’s breathability or appearance. Unlike some other sprays I tried, this product didn’t leave a sticky or stiff residue, which is a huge plus in my book.
Key Benefits I Noticed
- Restores Water Repellency: After applying, water beads up and rolls off immediately, which is perfect for staying dry outdoors.
- Protects Against Stains: It repels dirt and oils, making my gear easier to clean.
- Safe on Various Fabrics: I used it on both synthetic and natural fabrics without any discoloration.
- Easy to Apply: The spray nozzle delivers an even coat, and it dries quickly.
How I Apply 303 High Tech Fabric Guard
- Clean the Fabric First: I always make sure my gear is clean and dry before application.
- Spray Evenly: Holding the bottle about 6-8 inches away, I spray a light, even coat across the entire surface.
- Let It Dry: It usually takes a few hours to dry completely, but I avoid using the items until fully cured.
- Repeat If Needed: For older or heavily used fabrics, I sometimes apply a second coat to maximize protection.
Things to Keep in Mind
- It’s best used on clean fabric — dirt or oils can prevent proper adhesion.
- Not suitable for use on leather or suede.
- While it enhances water repellency, it won’t make fabric 100% waterproof.
- I recommend using it in a well-ventilated area due to the spray’s fumes.
Where to Buy and Price Considerations
I found 303 High Tech Fabric Guard available in most outdoor stores and online retailers. The price is reasonable for the amount you get and the protection it offers. Buying from a trusted retailer ensures you get the genuine product.
