With masking puddy demarcating first pattern, all other areas covered with paint trimming masking tape.
Blue paint trim tape has more adhesive power than Purple paint trim tape. Thus used Purple tape more since risk of tape pulling paint off already painted surface is less.
However, Purple tape does not contour well over irregular surface or sharp edges, hence use Blue trim tape on top of Purple tape for snugged fit. Do not use regular Beige masking tape on models, for it will pull paint off painted surface. |
