By sealing the fabric, we keep the cockpit dry, but also slow down the development of mold and stains on the canvas.

This one isn’t cheap but it works, though it smells very much like it contains the same stuff as Fabsil. ## Features - Flammable liquid and vapour. - Harmful if swallowed. - Harmful to aquatic life with long lasting effects. - May be fatal if swallowed and enters airways. - May cause drowsiness or dizziness. - Strengthens and Restores Lost Water Properties For Marine Fabrics - Recommended by Sunbrella, Leading Outdoor Fabric Manufacturer - Protects Against Water-Based Stains - Does Not Alter Fabric Color, Feel, Flammability, or Breathability - Safe For Synthetic and Natural Fibers In Marine Environments ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0000AY1W7 | | Best Sellers Rank | 357,696 in Automotive ( See Top 100 in Automotive ) 20,091 in Car & Motorbike Care | | Brand | 303 Products | | Brand Name | 303 Products | | Capacity | 128 Fluid ounces | | Contains Liquid Contents? | Yes | | Customer Reviews | 4.5 out of 5 stars 2,222 Reviews | | Global Trade Identification Number | 00082043006706 | | Included Components | One Bottle | | Item Form | Spray | | Item Type Name | UV Protectant | | Item Volume | 128 Fluid Ounces | | Item Weight | 6.73 Pounds | | Item form | Spray | | Item volume | 128 Fluid Ounces | | Manufacturer | Gold Eagle | | Material Features | Fragrance Free | | Material feature | Fragrance Free | | Model Number | 30674 | | Number of Items | 1 | | Part Number | 30674 | | Product Warranty | Everything you purchase from us comes with a 100% Satisfaction Guarantee.

It took 2 gallons to fully saturate the bow cover and mooring cover. I used a pump sprayer. I wish it went further and I would have sprayed the other sides, but 1 application cost over $150 and probably saturated through to the other side anyway. **Q: Can 303 be used in a washing machine** A: I do not recall if it specifically states that it can or cannot be used in a washing machine. We have only used it to spray the outdoor furniture, i.e. fabric cushions, etc to make them resistant to rain and water. If used as directed rain and/or water will bead up and not penetrate the fabric cushions. **Q: The description says it is for. Carpet. Does that include household carpet?** A: Yes you can use this on non-vinyl/plastic carpet. However it does produce a strong odor for 2-3 days after application, so if indoors you will want to apply it only on those days where you can open all doors, windows, etc. for adequate ventilation. In our case we often leave for the first night or so to avoid the odor. After adequate drying there is no residual smell nor any discoloration of materials. As for effectiveness, it is an excellent product that protects for several years. Also, you need to know that there are two similar products. One provides UV protection only. The other has a wax additive that adds waterproofing. We use the latter on all outdoor applications. Both have given us excellent protection aboard our sailboat. What else is there to say? We like and have used these two products for years. Good luck and may the wind favor your application. **Q: Is this ok on vinyl** A: this product is only for fabric. Use 303 Products 30350 Aerospace Protectant for anything else: vinyl, leather, plastic, etc. I have used both products and they perform great! ## Customer Reviews ### ⭐⭐⭐⭐⭐ Keeps our boat looking good. *by M***N on 7 December 2025* We apply this every year to the canvas cockpit enclosure of our boat.

I purchased a used boat that has 2 canvas covers. The covers are in good condition but leaked a significant amount of water. This product saved my boat covers! I'm so happy I spent the money and went with this brand!!! I was considering a cheaper brand, but 2 things made me decide to order this one: the videos that others posted that showed them pouring water on the surface (that's exactly how it works!) and the fact that my local marina sells only this brand (for a whopping $168!) I didn't skimp - I first washed the entire canvas with the recommended 303 Multi-Surface Cleaner, rinsed well and dried overnight. I didn't actually use a garden sprayer. I used a heavy-duty industrial spray bottle (to control the application and the "overspray") and thoroughly sprayed it on in sections. It was a very hot, sunny day, so it dried very quickly. (I left the canvas attached to the boat for the application, so I was very careful to mask off the surfaces I didn't want sprayed!) I left it to dry overnight. The next morning, I did my water test by pouring a large jug of water over it. It worked just like the videos! The water beads up and rolls right off!!! I'm SO happy with this stuff, I've now used it on my cheap, not-waterproof outdoor patio cushions and toss pillows! The money I've saved just by not having to replace outdoor cushions would have justified the cost of this product, but it has also saved me a few thousand in replacing my boat covers! Highly recommended! ## Frequently Bought Together - 303 Products Marine Fabric Guard – Water Repellent & Stain Shielding Fabric Spray, Safe for All Outdoor Upholstery, Simple & Easy to Use, Protectant Spray for Boats, 1 Gallon - 303 Products Multi-Surface Cleaner - Safely Cleans All Water Safe Surfaces, Including All Types of Fabric and Vinyl, Rinses Residue Free, Manufacturer Recommended, 1 Gallon (30570) - 303 (30306) Marine UV Protectant Trigger Sprayer, 32 fl.
