Top Gun or Sunbrella. I have a Sunbrella mooring cover that is going on 22 years old. Clean it once a year with mild soap and give it a coat of Scotch Guard every 3 years or so. I have, actually my lady has sewn it a few times where some seams separated but man it's 22 years old. I have been quoted 700 bucks CDN for a brand spanking new Sunbrella travel cover. That will save me $200.00 a year for shrink wrapping it. In my opinion there are only 2 choices. Those covers we can get from places like Canadian Tire stores are crappola and aren't exactly cheap up here. A good cover of Top Gun or Sunbrella is well worth the investment.
