Wax put over your applique adds a lovely finishing touch. And there is a good way and not so great way of getting this finish.
To get the best finish, put your first coat of wax on and wipe back straight away. If you let it dry and then try to wipe it back, it is likely the wax and paint will come off going back to the original colour of your applique.
Wipe back and let dry, add your second coat of wax (if you do) and gently wipe back. Wax over appliques only need be one coat.
