Common Questions
Is LLumar or 3M better quality?
Both are premium manufacturers with excellent quality control. There's no clear quality winner—both films are top-tier products that will last 15+ years with proper care.
Does 3M tint interfere with electronics?
No. 3M Crystalline uses non-metallic multi-layer optical technology and doesn't interfere with GPS, cell signals, Bluetooth, or radar-based safety systems.
Does LLumar tint interfere with electronics?
No. LLumar's ceramic films are also non-metallic and won't interfere with any vehicle electronics or signals.
Which is better for Tesla?
3M Crystalline is our top choice for Tesla glass roofs due to near-invisible 70/90 VLT options. LLumar IRX is excellent for side windows if you want darker tint.
Is the price difference worth it?
The $50-$100 difference between these films is minimal over their 15+ year lifespan. Choose based on your priorities (heat rejection vs VLT options) rather than price.
Can I mix LLumar and 3M on the same car?
You can, but we don't recommend it. Minor differences in appearance and aging could become visible over time. Pick one brand and stick with it.
Which lasts longer?
Both carry lifetime warranties and typically last 15+ years. There's no meaningful longevity difference between these premium films.
Which is easier to remove?
Both remove cleanly when removal is needed. Quality of removal depends more on installation age and condition than brand.
