Actually, there are couple other products that works really well on textured black plastic bumpers and parts.
1. Wizards Black Renew. Excellent cream type application that actually lasts.

2. Gatorback coating kit. Used on Avalanche and Escalade cladding and it is a permanent solution to faded textured black plastics.
