Did a great job applying Raptor bed liner material. The thickness of the roller was the right item for the thickness of the coating. However cleaning the roller is a different matter. Used mineral spirits to clean the roller. When I used it to second coat the next day found that much of the roller had embedded epoxy material. Was able to complete second coat but didn’t expect to be able to use it again and discarded it. Even with that, it was a very good purchase.
