There was a past thread about the stuff to use to
re-waterproof the boat covers, but cannot find it.
Can someone tell me the name of the product?

Go to the sunbrella web site.
Sunbrella recommends the following: copied from an i-boats thread. They recommend washing with woolite or ivory snow and cold water first, rinse and let dry in the air first.

Re-treating the fabric

As part of the finishing process, Sunbrella fabrics are treated with a fluorocarbon finish, which enhances water repellency. This finish is designed to last for several years, but must be replenished after a thorough cleaning. Based on test results, Glen Raven recommends 303 High Tech Fabric Guardâ„¢ as the preferred re-treatment product for Sunbrella fabrics. Fabrics should be retreated after thorough cleaning or after five years of use. Check with your local Sunbrella dealer or distributor for more information.

Applying 303 High Tech Fabric Guardâ„¢

303 should be applied to Sunbrella fabrics after each thorough cleaning, which typically removes the original fluorocarbon finish and reduces the fabric's water resistance. After cleaning the fabric, allow it to air dry completely and then apply 303 in a thin, even coat. After allowing the first coat of 303 to air dry, apply a second thin, even coating of 303. Two light coatings are more effective in restoring fabric water resistance than a single heavy coating. The 15-ounce aerosol provides coverage of up to 50 square feet of lightweight fabric.

One thing I heard from my canvas maker is spray the inside with silicone. The silicone is drawn through the fabric to the outside and will restore some water repelant qualities. I can not vouch for this, but it came from a reliable source.

OR, have a new cover made out of "Stamoid"...Its very lightweight, superstrong, and waterproof (It will NEVER need re-waterproofing) Mine is 10 years old and in new condition. The only maintenance is soap and water.

What about older non Sunbrella canvas? I'm assuming our's is as old as our boat, 1982.
