What changes after repeated spray exposure? In this LBFILM demonstration, five film samples go through three spray rounds and are checked for visible gloss loss and dull spots.
How the spray comparison was filmed
The five samples are treated through three visible spray rounds, then inspected. The video does not identify the spray formula or document calibrated volume, distance, dwell time, temperature, or a standardized laboratory procedure.
What was visible after three rounds
- LBFILM MT10 and Sample 4: no visible gloss loss or dull spots in the final inspection shown.
- Samples 1–3: visible changes were reported in the video.
These are visual observations from this session, not a universal ranking or long-term durability conclusion.
Why test conditions matter
A fair comparison keeps spray material, dose, distance, exposure time, temperature, cleaning method, and lighting consistent. Treat this as a practical demonstration, not standardized certification.
