After giving my black fabric convertible top a good wash, in preparation for the product, I realized I didn't need to dye it. I was just really dirty.
I gave it 4 stars because I couldn't figure out another choice. It did get here quickly. I'll keep it in case I ever do meed to use it. I used carpet cleaner, a soft brush and let is soak, by the way.
Easy to apply. The cleaner alone made a significant improvement in my rag top. The top looks good after completing the application, possibly too black. I expect the too harsh black will soften with a little time.
