Beardpower,
If by "rolling razor", you are referring to the HEADBLADE, shaving gel should not have shortened the life of the blade(s) in any way, shape, or form, but HeadBlade does have a complete line of shaving products to compliment their razor.
There is another brand razor out there actually called the "Rolling Razor" (completely different to the HeadBlade in shape , design, and performance) and it's unclear whether your making reference to that brand or referring to the HeadBlade itself as a "rolling razor" because of the little wheel on the rear of the unit.
There is a section on the forum dedicated to the HeadBlade and also a short video on the HB website that demonstrates how to get the best performance from your HB. Check it out, if you haven't already!!
