sorry to be confusing--the first door opener quit working after I replaced the battery. I had a second opener which also quit after replacing the battery. I now have two openers that no longer work. If your theory is correct, can you advise how to fix it? Thank you!

I have the same issue and for a long time I could not figure out how the rain water is landing on top the car especially after I weather-stripped the top and sides of the door - until today when I just happened to open the garage door to clean the water mess on the car, the water came pouring through the sectionals of the door! Now it is simply not just the few drops of water that is the nuisance - if your car has some or lots of) dust the water drops create a messy look after the water drops on the car dry out - it looks really yucky on most cars and especially on a black car! If you want to go out and it is still raining, sure, the mess will be washed off but what if it is bone dry outside (sunny or not) - one is compelled to wash the mess off oneself or take the car to the car wash, unless one is ok with a messy looking car. This is quite annoying if this happens frequently as it does in the rainy season.

I believe your garage door is only warrantied for acrylic or water-based paints. No spray paint. Get a good acrylic primer and then just paint the color you prefer.

I went with a LiftMaster shaft drive. Very pleased because it’s quiet for bedrooms above and opens space mid garage. This model has a security deadbolt when the door is closed, battery backup in event of power failure and is smartphone operable to check if closed or operate remotely.
