Step 10: Set the timer, a mere five minutes...
Use an online timer, your cell phone, your microwave clock timer,
whatever you can to ensure the cream is on your project for only five minutes.
In this five minutes, carefully wash your paintbrush and gently dry it. Wash
and dry your hands and head back to the timer. Ten, nine, eight.
Don't panic if you exceed the five minute limit by a bit.
