Instruction: Painting Lexan bodies with paint masks

Prepare the Lexan body as directed by the manufacturer. It is recommended to lightly scuff the inside of the body using 1500 grit sandpaper in any areas you will be applying water bases (Acrylic) paint. DO NOT scuff in any areas that will be left clear, tinted, chromed or, where ANY metalized paint will be applied.

Cut out the portion of the mask you want to use, with a sharp hobby knife or a pair of small scissors. Weed (remove) excess material you do not want in your design. We do not recommend that you weed any more of the mask than you are going to use right away.

Cut a piece of transfer tape big enough to cover the design you are working with. Apply the transfer tape to the mask. Rub it down well in one direction using a plastic card. DO NOT rub back and forth this will wrinkle the mask and make it hard to work with.

Turn the design over and roll the backing off the mask, being sure the entire design lifts with the transfer tape (Go slowly as not to tear the mask). Apply the mask to the Lexan body in the desired location. Start rubbing the mask down starting in the middle and working to the outside edges. Slowly remove the transfer tape at a 45 angle.

Using a good hobby masking tape, tape off all areas of the body where the mask needs to extend to. Also, tape off any other areas you do not want to paint. DO NOT use common masking tape, it will leave residue and crate paint bleed through.

Right before you are ready to paint the body, using a heat source (such as a blow dryer) to lightly(!) heat the mask. Then firmly press down the mask in the heated area.This will help mold the mask around corners and abrupt edges. Only heat a small portion of the mask at a time and continue this process until you have completely sealed the mask to the body. This will help prevent paint bleed through.

You may now begin to paint the body. Paint dark colors first working to lighter colors. If your paint scheme requires a light color to be applied first be sure to back it in white before applying dark colors. Allow paint to dry thoroughly. you can accelerate the drying process using your same heat source. CAUTION do not use a heat source until you are completely finished painting the entire area, this may cause the paint mask to lift.

Begin removing any masking tape followed by the paint mask. Try to peel in the paint mask in the direction of the design if possible. Then paint the area the mask was removed from. It is recommended to use some sort of sealer to help protect the acrylic paint. Allow to dry thoroughly.
