Canvak

Canvak is a canvas preservative for treating awnings, tarps, canvas covers and canvas tents.  It is easy to apply.  You can spray it on with a pump up weed sprayer, you can roll it on, or brush it on.  Canvak prolongs the life of older tents.  One gallon covers approximately 100 sq ft.  Canvak is not recommended on synthetic fabrics.
