What’s the difference in material between the Fel Pro 50145 R that most local jobbers sell and stock , and the Fel Pro 1612 as both are some kind of fiber

I have used both on factory straight and clean valve covers , and I definitely can recommend the one I wouldn’t use again on a factory valve cover
