If there is a gap when the car roll pan is installed, it may cause water, dust or air to seep into the compartment, and at the same time affect the appearance of the vehicle. Here are some possible workarounds:
1. Adjust the roll pan: First, check whether the roll pan is properly installed on the vehicle body. Sometimes, due to assembly or collision, etc., the roll pan may be slightly offset, resulting in a gap. You can try pushing or pulling the roll pan slightly to see if that aligns it and reduces the gap. This might solve the problem if you adjust for a smaller gap.
2. Adjust the latch of the door: Sometimes the gap of the roll pan may be caused by the incorrect location of the latch. You can try to loosen the lock screw on the roll pan, adjust the position of the lock slightly, and then tighten the screw again to see if the gap can be reduced.
3. Use sealing strips: You can buy sealing strips for cars and stick them on the edge of the roll pan to fill the gap and prevent water and dust from seeping into the compartment. Make sure to choose the weather strip that is right for your car model and install it correctly.
4. Seek professional help: If the above methods cannot solve the problem, or you are not sure how to operate, it is best to seek the help of a professional auto repair technician. They can inspect the fit of the roll pan and bodywork and advise on appropriate repairs.
For repairs and adjustments to your car, especially those involving bodywork and safety systems, always seek professional auto repair services. Improper handling may cause safety issues or further damage to the vehicle.
