If you are using bottled enamel, shake well before use.
Paint 1-2 light coats of enamel only. Using too much paint will result in rough surface after enamel setting procedure.
If you make a mistake, wipe off the paint before it dries off.
If enamel is too thick, dilute with a VERY tiny amount of water (less than a drop)
Wash your brush between each change of color. Dry the brush well on the paper towel before moving on to your next color.
Do not let enamel dry out on the paint brush as it will not come off when its dry.
