  2. Spray the surface cloth uniformly until it is moist, overlapping sprayed regions.
  3. For 303 fabric guard allow 6-12 for the fabric to dry completely. For marine fabric guard, allow 12-24 hours for the fabric to dry.
  4. Let it dry in a clean and dry environment till the treated material is entirely healed. It must also be sheltered from rain and dew.
  5. Note, that the product liquid and spray are combustible. So keep the product and treated material away from heat, sparks, and open flames until they are completely dry.

Which Fabric Guard Is The Best for You?

Both the fabric guards are quite the same. But we definitely recommend using a 303 marine fabric guard if you’re looking for something for your boat. Since 303 marina guard is made to serve that purpose.

If you want to use it for any other reasons, go for a 303 fabric guard. You can still use it for jackets, or any other fabric to resist water. But it won’t be as effective as 303 marine fabric guard.

How does 303 fabric Guard work?

303 Fabric Guard is a waterproofing spray that works by forming a protective barrier on the fabric that repels water and stains. The spray contains a proprietary formula that bonds with the fibers of the fabric, creating a hydrophobic (water-resistant) surface that helps to keep the fabric dry and protected.

When applied, the spray forms a clear, invisible barrier that does not affect the color or texture of the fabric. It can be used on a variety of outdoor fabrics, including Sunbrella, canvas, and nylon, and is effective in protecting against rain, snow, and other types of moisture.

303 Fabric Guard is easy to apply and can be sprayed directly onto the fabric using a spray bottle. The fabric should be clean and dry before application, and it is recommended to test the spray on a small, inconspicuous area of the fabric first to ensure that it does not affect the color or texture of the fabric.

It is important to follow the manufacturer’s instructions for application to ensure optimal performance and to reapply the spray periodically to maintain the water-resistant properties of the fabric.
