Bonus Heat Rejection Strategy

Customers drive in with SUVs and trucks already tinted from the factory. They ask you to “match the fronts,” assume the rear glass is fine, and leave potential comfort—plus profit—on the table. One simple demo changes that outcome every single time.

Step 1: Grab a Junkyard Window

I picked up a Chevy Silverado rear door glass at the dealership for about $80. A salvage yard would cost even less. Any factory-tinted piece works.

1. Flip it on the bench.
2. Tint half with a clear ceramic like Nanoflex 70%.
3. Leave the other half stock.

Now you have a portable “before vs. after” window.

Step 2: Fire Up the Heat Box

Place the bare-factory half in front of your heat lamp. Let the customer rest a hand behind it—heat spikes in seconds and the heat sheet glows.

Slide the glass two inches so the ceramic side faces the bulb and flip the lamp on again.

Result: The card stays cool and their hand barely notices any heat.

Step 3: Make the Simple Ask

“Do you want your rear windows to feel like the ceramic side or the factory side?”

No tech lecture, no spec sheet—just the feeling in their palm.

Why This Works

• Real glass, real proof: It is the same privacy glass they already have.
• Emotional close: Heat is personal; lab numbers are not.
• Clear upsell: One extra service boosts the ticket and delivers full-cabin comfort.

Quick Pricing Tip

Offer a flat add-on fee for “rear ceramic treatment.” Customers see value, installers keep workflow simple, and nobody feels nickeled-and-dimed.

Takeaway

Factory tint blocks light but does almost nothing for heat. Show that gap, fill it with a clear ceramic coat, and both your customer and your bottom line stay cool. All it takes is a junkyard window and a two-minute demo.
