I've tried a lot of different car washes and like Zymol the best. Unfortunately I can't find it anymore. The last car wash I used was Meguiar's Deep Crystal and Meguiar's Gold. Does anyone know where to get Zymol or have any recommendations?

 

I would suggest you try contacting them directly. Or check out some of the auto supply sights like
look here or another would be this site
You should be able to find a quality car wash or equivilent.

I use Mothers California Gold car wash....works really well and doesn't strip/remove the wax.....

 

I highly recommend 1Z Perls or Poorboys. Trust me, you won't regret it.
