01.
Weed all of the unusable portions of the mask. It helps to have a sharp hobby knife handy. After the weeding process you should be left with the paint mask only.
02.
Apply the transfer tape to the portion of the mask that will be applied first and rub down the transfer tape (A plastic card works well). Remove the paint mask and transfer tape from the mask backing and prepare to apply the mask to a clean, smooth, and flat surface.
03.
Apply the mask pressing down from one end to the other. Ensure that the mask is pressed well into all of the surface contours by using your fingernail and repeatedly rubbing the paint mask down. Peel away the transfer tape but don’t throw it away as it can be reused to apply the other pieces of the mask. If the paint mask doesn’t stick to the surface, then you DO NOT have a clean surface and have just contaminated the adhesive on the paint mask.
04.
Use high quality masking tape or some of the unused parts of the paint mask to extend the paint design into the neutral areas/ other parts that you don't want painted
05.
Just before painting, make sure that all of the edges of the mask are firmly pressed down to avoid “paint bleed”. The use of some sort of heat source such as a hair dryer makes it easier to press the paint mask firmly against the surface. DO NOT overheat the paint mask for it may leave adhesive on the surface.
You are now ready to paint. Use "Light" coats to help seal the edge of the mask and prevent "Paint Bleed".
06.
When pulling off the paint mask after painting, be sure to pull the mask parallel to the lines in the mask to ensure a clean edge. Also, allow sufficient time for the paint to dry to ensure a clean paint edge. You may use a heat source such as a hair dryer to accelerate the paint drying process. Again, DO NOT use too much heat.
