I had a question to what products will leave a nice matte finish, but not be so slippery to the touch. I ask because I have been detailing the police cruisers for my local town and the back seats are just a solid plastic bench. I have tried several Armor All's, and the 303 protectant. They seem to leave the plastic clean, but very slick. I'm sure any guests back there are going to enjoy sliding around a bit!!! Also, the floors are just a textured vinyl. No carpet or mats. I have been cleaning the floors with a brush and soapy water and sucking it up with a shop vac. Then going back with the 303 and going for the nice finished look. Again, a bit slick on the floor. Any suggestions? Thanks, Jim.
