This Is Not rocket science. CTS stucco mix and La Habra make a good product. I got a $6000 quote from a reputable company here in Tucson to fix cosmetic cracks and started watching Kirk Giordana on RU-vid and have become pretty darn good after buying the right tools and learning the process of applications. Good video here, but if you research this trade, you’ll get the hang of it. Buy a cheap cement backer board and practice.
