Tip one: Use a rubber protectant or silicone protectant on all door and window weather stripping. This is going to help it keep from cracking and leaking. You just want to make sure you use water or silicone based lubricant as oil based products will damage the rubber.

Tip two: Regularly clean and treat the car's weather stripping. This will mean that your car doors are less likely to stick to the rubber seal in cold weather, which means it is less likely to be damaged. It will also make doors easier to open, especially for children. If you feel your weather stripping sticking to your door, wipe it down and give it a thorough cleaning.

Tip three: Fix or replace bad weather stripping as quickly as possible. You want to make sure that it is not leaking any rainwater into your car interior, as this can ruin it very quickly. So, take a look at it, and decide if it can be fixed, or if it is so far gone that it needs to be replaced. If it has cracks, or small leaks, you can probably use a brush on sealer to fix the seams. If it is lose, you will need to secure it with trim adhesive. If it is torn, visit your auto parts store and see if you can pick up some caulking made especially for that. You can also make worn out but intact sections last longer by inserting foam rods into them. You can usually pick these up at auto part stores.

Tip four: If you need to replace weather stripping, do not replace it with a generic type, rather with the kind that is made specifically for your car, even if you have to special order it. It will be worth it, as it will last longer, and work better, which means your interior will be protected longer.

Don't forget, the weather stripping on your car adds comfort, but it also prolongs the life of your car interior, so do not let it fall into disrepair. It is vital that you pay attention to it and not let it get or stay damaged for long.
