Blow or wipe the dust off the enclosure. Then, spray it down with a good grease remover like this PCL Aero Prep. Wipe the Aero Prep with a clean rag and repeat until no dirt shows on the rag. Just before painting, wipe a tack cloth over the surface to remove any remaining dust or rag lint. Be sure to wear latex gloves to avoid getting hand oil on the surface since this will prevent the paint from adhering properly. We use BASF Glasurit paint, and this is the color coat, or basecoat.
Mix two parts paint, silver in this case, with one part reducer. Use a paint strainer when pouring the paint into the paint gun to avoid contaminates. Spray two to three wet coats of color on the surface, allowing 10 minutes between coats. Clearcoat is the next step, providing protection and shine for the color coat. This BASF R-M clear is mixed four parts clearcoat, one part hardener, and one part reducer. Spray two to three wet coats of clear over the color coat and allow 12 hours to dry. We wet sand and buff the paint most of the time, but it's not necessary in this case since these enclosures will be on top of a 10-foot roof.
Last month, we fiberglassed the speaker enclosures for the top of the RV. Now that the fiberglass has cured we can finish the construction process. After the carpet has been fiberglassed, it ends up with a rough texture. This texture must be removed with an angle die grinder. A rough 24-grit disc works best to smooth out this texture quickly. These enclosures will be exposed to the elements on the roof of the RV, so we decided to use PVC pipe to run the speaker wire. A 90-degree elbow fitting was molded into the back of each enclosure to allow 3/4-inch pipe to fit inside. The 90-degree elbows were tacked in place temporarily using superglue and permanently attached with fiberglass-reinforced body filler.
Rage Gold body filler can now be applied to the surface of each enclosure to fine-tune the shape. This picture shows the proper ratio of filler to hardener. A scrap of wood or cardboard makes a great mixing board. The Rage Gold is spread evenly over the enclosure surface using a spreader. Wearing latex gloves, use your finger to smooth out tight spots. The Rage Gold will start to cure in five to 10 minutes and will have a clay-like consistency for another 10 minutes unti...
