How do you wash it Fitz?My canvas guy said to use a pressurewasher. My 230 cover is now 5 yrs old and getting pretty mildewy again - I did scrub it a couple times with a little bleach in the soapy water, no p-washer yet. Came out much cleaner - it's a big cover and kinda hard to handle so I'm sure I didn't get it real clean. My canvas guy said no bleach although Sunbrella site says ok.My 170 cover gets mildewy real quick :(
I know that Sunbrella recommends 303, my canvas guy said Scotchguard and that is less than $50 / gal.
The issue with Scotchguard so I hear is that it is silicone based and you are not supposed to use it on Sunbrella. The 303 is ridiculously expensive @$100 a gallon and my cover needs a gallon to be re-waterproofed so I'm all ears for an alternative.

Works great and easy to apply. I used a Garden type pump sprayer and applied the product while it was on the boat. Used a little over 1/2gallon for my 19-6 and the cost was around $40-50.http://www.starbrite.com/productdetail. ... ductSSCat=And an video http://www.starbrite.com/videos.cfm?ID=35
