Learning How to lay down a decent paint job will take a little while to get the process down and let it get absorbed into your brain. The more models, or anything you paint, the better you will get. Try to remember the steps mentioned here, but the tips are only 30 percent of it. the other 70 percent is trial, error, experience, and PATIENCE. Even the best painters run into unexpected problems sometimes. Try not to let messups get you down, but think about why they may have happened and try to learn from your mistakes. Take your time, let things dry completely. After a few paint jobs you will learn what works best for you. Some people prefer different products, primes etc... Just find what works for you. And dont think of a messup as a failure, its just learning how to succeed!
