One of the most important things to remember when trying to achieve a clean tape edge is "less is more" The higher the film build is on the graphic, the greater the chances are of the paint bridging onto the tape. When the tape is removed it creates a jagged line where the bridged paint is torn. Like Scott, I use my airbrush or my Spot repair gun (Devilbiss SRi)to shoot the flames. When using pearls for flames, I like to pull the part off of the stand and rotate it to see the reflectiveness of the pearl platelettes. once I achieve a good even flow, I stop and pull the tape. This is also where contrast of colors comes into play. The more color it takes to create a contrast on the base color, the higher the film build and the more likely a jagged edged tapeline is to occur. Also make sure that you clean along the tape edge with grease and wax remover before spraying the flames, so that youre not painting the glue from the tape (blue fineline is bad for this). When removing the tape, use quick even pulls toward the flame (this makes a cutting action). Also make sure to clean the tape adhesive off of the flame paint edge before clearing (be careful the g&w remover will take off basecoat).
