vinyl protectant for tonneau covers

[DownSouth]

Is there a vinyl protectant for tonneau covers that will not wash away and streak down the sides of the truck when it rains? I've tried both 303 and Vinylex and they both streak, although Vinylex does it to a lesser degree. And yes, I did wipe off the excess following applying the product.



Thanks

I use 303 and wipe in down with a dry MF after say 30 minutes.
