I use masking tape cut to fit the opening on the seat belt hardware. Put it through a bit and fold it over and it sticks to itself. then turn it over sticky side down and place it on waxed paper and paint it any color you want. When dry put it on the seat, it sticks by itself and cut off any excess. I usually put a dab of epoxy on the underside of the seat belt hardware resting on the seat, and also on the other end of the seat belt so it NEVER comes off. This method also works with shoulder harnesses too, and works for me. Try it!
