I watch so many videos of this product including yours and no one mention they you need to dilute the paint 4 parts black 1 water if too is canvas…I eventually discover this on the package (how dumb of me, of relaying on RU-vid instead of resign!).The paint is so think that is impossible to make one too with just 1 bottle. Well you just need to add water and make it much easier and better!
Never pressure wash your soft top a gentle hose down is the way. Prior to cleaning wet you canvas down with vinegar to kill of the green mildew then rinse and then continue with the cleaner.
Well after watching that video I'm definitely not going to use that nasty cleaner, there has to be better products out there on the market. Sorry to say this but that roof that you did looks like crap.
