Painting Dark Wine Bottles - Tips & Tricks?

Hello fellow DIY brides!

I’ve started working on a centerpiece project that I’ve been happily collecting wine bottles for! 🍷

I’d like them to all be painted white, and have started the spray painting process, and while I’ve spray painted a good amount of things before, it’s been taking *forever* to get enough coats to cover the bottles since they are all dark (I personally prefer red wine lol). Has anyone faced this problem before, or are there any spray painting gurus out there that can recommend any awesome products or tricks? Any help is greatly appreciated!
