I also need something that works. Here's one I'm thinking about trying. STARBRITE WATERPROOFING Has anyone tried it? A lot of amazon's reviewers are using it on patio furniture, boat covers, etc. Most of the bad reviews are about the crap spray bottle, not the product. Note that it comes in a 22oz spray bottle. For twice the money, you can get almost 6x more in a gal jug. Just put it in a spray bottle from Wally's.
Supposedly you get better penetration if you cut it 50-50 with denatured alcohol.
