I prefer the Renovo UltraProofer, it paints on thick, and there is no need to worry about getting it on the paint. Raggtop is just as good, it's just preference for painting it on or spraying it.
I doubt you have done any real damage, but I wouldn't use it. Get the correct stuff from Renovo or go with Raggtop or 303. It's all preference because most of the canvas cleaners/waterproofers work just as well as others.
