5. Grit anD usaGe—Sanding with different grades of sandpaper is the technique for creating the desired levels of "wear." The more distressed you'd like the finish to appear, the heavier grit you should start with. In this case, Jeremy began sanding with 400 grit paper and moved up to 800 grit. "You'll use a ton making this effect," Jeremy warns. 1. appLYinG "primer" coLors—Gray and red were common colors for primers on older builds, but you should research the colors you want to reveal through the "distressed" topcoat. In this example, we sealed the hood with ECS25 Gray A-Chromatic LV Sealer, and then applied color coats of T436 Red Oxide until hiding was achieved. 6. DuLL GLoss—Weathered, painted parts typically have lost their gloss. So another key to achieving the distressed patina look is the use of a matte or flattened clearcoat. And here you have several options. On this hood, Jeremy used Global Refinish System ® D8113 Matte Clearcoat. Other well-suited choices include adding a flattening agent to Deltron ® clearcoats like DC3000 High Velocity Clear, DC3010 High Velocity Clear LV, DC4000 Velocity Premium Clear or DC4010 Velocity Premium Clear LV. 2. DrYinG—It's critical that each layer dry completely before applying the next coat. Smooth, predictable sanding is important to the patina affect, and if the layers have not completely dried, the paint can tear. On this project, Jeremy used a hand-held, Venturi-type blower to thoroughly air dry the basecoat and ensure sanding quality. 3. topcoat coLor—As you research colors for the year you're looking for, you'll find a tremendous variety of solid colors to choose from. For historical accuracy and overall effect, pearls and metallics are not usually selected as the topcoat color. In this example Jeremy applied three coats of a 50-50 mix of black EHP basecoat T407 and T409. 4. sanDinG—Before exposing the underlying colors, think about how your project vehicle would weather naturally. The front would take the most abuse, so you'll want the most exposure of underlying coats there, gradually lessening as you move to the rear. In addition, high points would wear faster. On this hood, Jeremy targeted these areas for extra sanding to reveal both the gray and red layers. If you remove too much color, you can easily repaint and re-sand the area. 6 22 1 2 3 4 5 here's hoW JeremY transformeD an oLD chevY cavaLier hooD.
