Raggtop is a paraffin wax based product. For best results, it should be applied on a warm sunny day. Apply the spray evenly and let cure for a minimum of 1 hour between coats. This allows the wax to bond to the fabric.
If applied in cool weather, the wax ingredient really doesn't have a chance to bond and just sits on the surface of the fabric where it will wash off in a hard rain.
I suggest you wait for a dry warm sunny day and reapply it again in the sun to a clean top and you will have better success and you'll see the difference.
