The homepage slider does not effectively communicate exactly what you do. "Total Solution in Auto Components..." doesn't tell me what you do. You do a better job in your products page with the "We specialize in Sheet Metal and Precision Fabricated assemblies of various industrial applications."

When you promote your business, whether it's on the homepage or with ads/content/PR etc, you need to be very clear in your messaging, specifically what it is that you do, who you do it for, and what the benefit (not feature!) is for the customer.
