The main difference between Crep Protect and Jason Markk Repel is that Crep Protect uses an invisible coating to protect shoes, while Jason Markk Repel relies on a soap-based solution.
Crep Protect is a water-based product that forms an invisible barrier on the surface of your shoes. It's safe to use on all materials, and it won't alter the appearance or color of your shoes. It's also safe to use on all materials, but it may cause colors to fade over time. Jason Markk Repel, on the other hand, is a soap-based solution that cleans and protects your shoes with each application.
