Having beautiful women in skimpy bikinis has been going on for decades in car magazines and at car shows. I believe the women make it seem like your car will be beautiful enough by using their products to be worthy of being at a car show with beautiful women, or in a magazine.
If women posing for pictures in bikinis is degrading to women, then so is women wearing bikinis anywhere. I would make the case that what is REALLY degrading to women is to mandate that they be covered at all times, like in the Middle East. THAT is the subjugation of women. Women being able to wear what they want and being free to make money doing it by posing in pictures is empowering to women. They do it of their own free will. It treats women as sex objects? As Hugh Hefner said, women ARE sex objects, otherwise the species would not perpetuate itself. For that matter, men are sex objects, too. All human bodies are sex objects. It perpetuates the species.
Is portraying men or women as sex objects degrading to humanity? It might not exactly point out the actual effectiveness of the products, and so is a bit of a distraction, but it adds glamor and appeal, and adds relevance to the human life experience,IMO.
Back on topic, though, I really like chemical guys E-Zyme , their synthetic quick detailer and their Grime Reaper.
