Most of our customers purchase Ceramic or Crystalline, so tinting the windshield comes up often when they are looking for heat rejection. I would say 60% of the time they ask for it, 40% of the time we promote it. We let them know if they are looking to block heat, then they should think about tinting the windshield because it is the biggest window in their vehicle. We let them know we have 50% if they are looking to add a little shade to it or up to 80%/90% if they would like to keep it clear. We then let them know that technically it is illegal to tint the windshield which is why we carry such light shades to ensure it won't be noticed. Our goal has always been to be honest, explain the pros/cons including it being illegal and let the customer decide for themselves.
