DETAIL & PAINT - Paint

1. For the finish coats, automotive grade acrylic lacquers or enamel hobby paints are recommended. Floquil railroad paints were used for this project. The paint scheme for Permit boats' was as follows: upper hull to midline - flat black; lower hull from midline down - red oxide. The propeller should be painted gold to simulate the bronze color of the original.

Wipe down the entire hull with a lint free rag and be sure to remove all dust from the scribed detail. Lay out parts on the work space. Observe all safety precautions when working with solvent based paint including breathing mask and proper ventilation.

2. Before you begin, make sure all objects to be sprayed is dry and clean of all dirt, grease or fingerprint oil. Spray the lower hull and rudder with red oxide. Mix the paint per instructions. Here, a double action air brush was utilized. Long thin strokes should be used until the entire surface is covered. Allow the hull to dry.

3. Wet sand hull with 1200 grit paper. Avoid sanding down to primer. Repeat steps 3 - 4 for two more applications.
4. Mask off the lower hull down the midline and stern planes (use 3M 1/4" or 1/8" tape). Prepare the flat black for spraying per manufacturer's instructions. Spray a thin coat to lower & upper hulls, sail and upper rudder.
5. Wet sand the hull and pieces with 1200 grit paper. Avoid sanding down to primer. Repeat steps 3 - 4 for two more applications or until the desired finish is achieved.
6. Place the propeller in a small cup and spray the back side with gold. Once it is dry, place it on a rod and shoot the top side. Use a fine tip to get good coverage around the hub between the blades. Buff with 0000 steel wool.
 

7. With the boat painted, protect the finish with an application of clear flat lacquer. Spray a thin coat over the entire model and let it dry. Then, rub with 0000 steel wool to further buff the finish.

Repeat 2 - 3 times to build a good tough barrier.

A Word of Advice...

Great effort goes into an outstanding paint job on any boat. If you are a novice r/c sub driver, consider postponing the final finish painting until you've run your boat several times in primer. The water won't hurt the primer and it could save having to repair assorted dings and scrapes generated during the initial shakedown period at the pond.

A Painter's Trick:

When masking off an area, shoot a thin coat of clear over the seam prior to shooting the new color. This will prevent bleed-through under the tape.
