## Description

303 MARINE FABRIC GUARD 128 OZ

Review: This product (High Tech Fabric Guard 30674) works great - 100% of the water now beads up and my cloth top looks better than new !!! My Situation: The very first time my brand new, light beige cloth convertible top got wet I realized it came from the car dealer and/or factory either untreated and/or seriously under treated because water just soaked right into the cloth as evidenced by the darker cloth color when wet. End Result: After applying two coats of this product 100% of the water beaded-up and rolled right off the top. Nothing soaked in at all - zero wet spots on the cloth top. (Since the top is a light beige color any wet spots would show up slightly darker in color.) Any water that didn't roll off the top was absorbed using The Absorber 51149 sponge-cloth available on desertcart or at WalMart. Process: 1) I gently cleaned my cloth convertible top using 303 Fabric Top Cleaner (303-30550). To do this I first rinsed the top with fresh water, then sprayed the cleaner on & gently scrubbed using a very soft brush (I used Star Brite Soft Yellow Wash Brush 040013 available on desertcart). A stiffer brush or too vigorous scrubbing could damage the fabric, scuffing the threads and creating a fuzzy look to the fabric. I cleaned the top in slightly overlapping areas about 18” x 18”. 2) I rinsed the top and allowed it to dry thoroughly. 3) Using a 2" paint brush and small container of 303 High Tech Fabric Guard 30674, I applied the Fabric Guard brushing it on in a manner similar to painting. By overlapping slightly I made certain I applied the product to every square inch of the top. 4) I allowed the top to dry several hours and applied a second coat of Fabric Guard. Notes: 1) When applying the clear Fabric Guard liquid with a 2" paint brush it will start to have a slightly white/foamy appearance - this will go away completely and the product will dry clear. 2) After each application I noticed a VERY slight, very fine clear crystalline residue on my cloth top. You had to look very closely to see it - it had just a little bit of sparkle to it in the sunlight. This brushed off quickly and easily & probably would have blown off the first time I drove the car. 3) Some reviewers seem to have issues relating to getting the product on the car itself saying it was hard to remove. I didn’t have this problem. The few times that I over-brushed or got small drops Fabric Guard on the car itself I simply gently wiped it with a soft paper towel and it didn't damage anything or leave any residual coating. It seemed to wipe off 100% with a soft paper towel. 4) READ THE LABEL !!! The first paragraph covers some surfaces that you CANNOT use this product on without causing damage. These include rubber, vinyl, clear vinyl, plastics, etc. Since the product's Material Safety Data Sheet lists the contents as Petroleum Distillates, just a wild guess but prolonged contact with this product may have a solvent effect on materials such as vinyl or plastic. 5) I wouldn't purchase 303 Fabric Cleaner again – I think a bucket of hot water with a scant squirt of Dawn dish detergent would do just as good of a job. Of course, you will need to completely rinse the top and allow it dry thoroughly before applying 303 Fabric Guard. 6) I have no idea how long my cloth top will remain water repellant after applying Fabric Guard. I plan on doing this process every 6 to 8 months or sooner if I notice any water being absorbed by the cloth top.
Review: We apply this every year to the canvas cockpit enclosure of our boat. By sealing the fabric, we keep the cockpit dry, but also slow down the development of mold and stains on the canvas.

## Questions & Answers

**Q: What is the coverage per gallon?**
A: Boat Cover :
I have a 24 foot open bow boat. 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!

I’ve tried several brands of products for waterproofing. This one isn’t cheap but it works, though it smells very much like it contains the same stuff as Fabsil.
