How to waterproof the doors of the new Regal?
3 Answers
The waterproof and soundproof strips on the door edges are severely aged. The owner can see leakage points on the door. Later, it is only necessary to replace the new waterproof and soundproof strips. If you find a lot of water accumulation in the door, you need to check whether the drainage holes are blocked. If there is a blockage, just unclog it.
After purchasing the new Regal, I paid special attention to the door waterproofing issue because water seeping in during rainy days is quite annoying. The new Regal's door design incorporates a waterproofing system that primarily relies on rubber sealing strips around the door frame to block rainwater from seeping in, with small drainage holes at the bottom to allow water to flow out. If water accidentally leaks in, first check if the sealing strips are intact—if they're too old or cracked, their effectiveness is compromised, and they should be replaced promptly. The drainage holes are located at the bottom edge of the door and can easily get clogged by mud or leaves; I use a thin metal rod to clean them out. Daily maintenance is simple: after washing the car, dry the door seams to prevent rust; before the rainy season, check the elasticity of the sealing strips to ensure a tight fit. Drive slowly through puddles to avoid excessive water pressure forcing its way in. Don’t underestimate waterproofing—a damp cabin can lead to musty odors and damage electronic components, but regular maintenance can prevent these issues. Overall, the new Regal's design is quite good, and with a little attention, there shouldn’t be any major problems.
Our family has been using the new Regal for over a year, and door waterproofing is a crucial aspect for family vehicles, especially with children who are sensitive to humidity inside the car. The new Regal primarily relies on the door frame sealing strips for initial protection, preventing rainwater from seeping through gaps, while accumulated water is drained through the bottom drainage holes. For maintenance, I inspect the sealing strips monthly for any signs of wear or deformation and replace them if necessary; cleaning the drainage holes is simple—just gently brush away dust with a brush to prevent leaves from clogging them. If water leakage is detected, it might be due to aging sealing strips or blocked drainage holes, which can often be addressed initially by oneself. Additionally, try to park the vehicle away from waterlogged areas to avoid water submersion at the door bottom leading to intrusion. The waterproof membrane inside may also allow water ingress if aged, but it generally remains effective for several years. Remember, prevention is better than cure—keeping the interior dry enhances comfort.
