Reflection boards make lows, highs, crowns, and waves visible during PDR repair.<\/figcaption><\/figure>\n

A PDR line board or LED reflection light helps technicians see dents by showing how straight lines bend across the panel. It is one of the most important tools for repair accuracy.<\/p>\n

Quick answer:<\/strong> A PDR line board makes lows, highs, crowns, and tool marks visible through reflection. It is a control tool for diagnosis, pushing, glue pulling, finishing, and final inspection.<\/p>\n

1. What does a PDR line board do?<\/h2>\n

It reflects lines across the panel so lows, highs, crowns, and waves become visible.<\/p>\n

2. Do beginners need a line board?<\/h2>\n

Yes. A line board helps beginners see what the tool is doing instead of guessing.<\/p>\n

3. What do bent lines mean?<\/h2>\n

Bent lines show that the panel surface is distorted. The direction of the bend helps identify lows and highs.<\/p>\n

4. What is the difference between a line board and an LED PDR light?<\/h2>\n

Both reveal reflection. A striped board gives strong line contrast. An LED light may offer adjustable brightness and mobile mounting.<\/p>\n

5. What is a fog board?<\/h2>\n

A fog board or gradient board helps reveal subtle waves and finishing texture, especially near the end of repair.<\/p>\n

6. Why is there too much glare?<\/h2>\n

The board may be too close, too bright, or at the wrong angle. Reposition the light until the lines are readable.<\/p>\n

7. Can a normal flashlight replace a PDR light?<\/h2>\n

No. A normal flashlight can show damage, but it does not provide the structured reflection needed for accurate PDR finishing.<\/p>\n

8. Why does battery power matter?<\/h2>\n

Mobile technicians need reliable battery power. A light board that only works when plugged in can slow mobile repair.<\/p>\n

9. Can a line board show cracked paint?<\/h2>\n

It can reveal texture changes, but paint cracks require close visual inspection.<\/p>\n

10. What should distributors check in line boards?<\/h2>\n

Brightness, contrast, mounting stability, power interface, cable durability, battery support, packaging, and replacement accessories.<\/p>\n
