## Questions & Answers

**Q: How much coverage per ounce**
A: 64 sq. ft....Required the whole 32 oz. spray for complete coverage.  Applied two slightly damp, cross-hatch coat coverage on an 8ftx8ft poly canvas Bimini top that was very much in need of treatment.   First rain beaded very nicely, but there were a couple of minor drip points, probably due to missed coverage. Will be applying another 32 oz treatment to ensure absolute leak free. Sprayer has option for stream or mist. Pleased with product.

**Q: If a fabric convertible top treated with 303 Fabric Guard is washed with 303 Cleaner or standard car shampoo, is the effective protection reduced?**
A: 303 Fabric Guard works best on untreated, not washed with fabric softener (Downey), tightly woven cotton fabric.  It will soak into the cotton and resist some detergent washing.  Your convertible top and Sunbrella fabric are already treated and this stuff will just sit on top and will wash away pretty easily.  303 works great on my Filson dry finish canvas jacket but washes off my Sunbrella outdoor seat cushions.  Any water repellant finish is ruined by fabric softener which persists in the fabric even after repeated rinsing so just hose off your outdoor seat cushions.

**Q: How does this work on personal items?  Like a wool coat?  I've heard rumors that it works, but I would love some first-hand accounts.**
A: I have not tried it on anything except my soft top convertable, I would think it would work just find, it does not leave any residue once it dries, it will smell for a day or so, but most repellents do.

**Q: Can you use this product on upholstery in a new car?  How does it compare with the Honda's "deal" of around $400-$450 for Fabri-Gard treatment by them**
A: Always Spot Test the fabric. I have used 303 Fabric Guard on canvas, boat carpet, indoor carpet, fabric and directly applied it to foam with no problems. Excellent water repellent.  Recommended for use by & on Sunbrella Material. A pleasant smelling light oily clear fluid that dries with no odor and no oily feel.  Can be sprayed, brushed, rolled and/or saturated. I suggest buying the gallon size. Not familiar with Honda's Fabric-Gard but For $400-$450 you could have a car seat or two recovered or replaced. Good Luck!

*by C***L on March 25, 2025*

THE GRACIOUS I'M SO SHOCKED!!! This is to make any fabric waterproof and when they said to lightly missed it one time and then repeat a second time it worked better than I thought there was actually way more in the bottle I thought it was going to run out cuz of all the things that I needed to waterproof but I think if I would have done it like I wanted to then there wouldn't been enough for all the products that I had to make them water resistant or waterproof to be more precise This is truly a remarkable product that does exactly what it claims to do

### ⭐⭐⭐⭐⭐ Beads water like a champ
*by D***E on May 17, 2025*
