303 Marine Fabric Guard – 1 Gallon

If you treat a lot of fabric, the gallon is the way to buy 303 Fabric Guard. Fill a pump sprayer and do the motorcycle covers, the shelter, the boat cover, the awnings and the patio cushions in one go.

It restores lost water and stain repellency on clean, dry fabric, back to straight-from-the-factory levels, according to 303. When rain soaks into a cover instead of beading off, the repellency is gone, and this puts it back.

• Protects against water-based and oil-based stains.
• Safe for synthetic and natural fibers.
• Doesn’t change color, feel, flammability or breathability.
• Recommended by a leading outdoor fabric maker.
• Made in the USA.

Before you spray: clean the fabric and let it dry completely. 303 recommends its Tonneau Cover & Convertible Top Cleaner for fabric and vinyl tops. Test a small hidden area first.

Shops, marinas, RV parks and riding clubs are who this size is for. For one cover, the 16 oz or 32 oz bottle is plenty.

Common Questions

Why buy 303 Fabric Guard by the gallon?
For big jobs and refills: boat covers, awnings, Dacron sails and several bike covers. It’s the same formula as the spray bottles.

Does Fabric Guard change the color of the fabric?
No. 303 says it doesn’t change a fabric’s color, feel, flammability or breathability. The cover keeps the look and feel it had, with water beading up again.

Can I use 303 Fabric Guard on outdoor leather seats?
303 lists outdoor leather seats along with boat covers, awnings and sails. Apply it to clean, dry material and test a hidden spot first.
