Painting and Masking Foam Surfaces

Finish the surface of the aircraft as described in "HOW TO FINISH FOAM SURFACES. This is a MUST.

Paint over the area that you want to mask an inch or so more than you want with the lightest paint you are using first.  Let this fully dry for a few hours.  Next apply the masking tape.

After you have applied the tape, paint with the light color over it overlapping into the 1 inch area of the light paint. This will seal the tape along the color line.  Let this dry for 1 to 2 hours maximum.  Next apply the darker color over the taped area overlaping the tape thick enough to hide the lighter color.  Let this dry for about a 1/2 hour to 1 hour maximum and carefully remove the tape at a very sharp angle.  You should have a great straight line between the two colors.  Let the darker color dry and then finish applying the darker color to the rest of the airplane.
