What are the best techniques for applying porcelain paint to a toilet bowl for a durable and long-lasting finish?

To achieve a durable and long-lasting finish when applying porcelain paint to a toilet bowl, it is recommended to thoroughly clean and dry the surface before painting. Use a high-quality porcelain paint specifically designed for bathroom fixtures, and apply multiple thin coats for even coverage. Allow each coat to dry completely before applying the next one. Finish with a clear sealant to protect the paint from water and wear.
