How do you repair holes in metal siding on trailer.

Sand down the edges of the hole. Repair the insulation located behind the sliding if deep holed. Apply a heavy bead of silicone sealant around the outside perimeter of the repair patch using the caulking gun loaded with a tube of silicone. Mix auto body filler apply to the hole and let dry before sand flushing.

Next apply some metal primer to the exposed edges and let it dry. Rub the edge of the hole down with soapy water but be very careful not to cut yourself while doing it as the edge of the hole may be very sharp. Sand the corners of the area you cut and lightly sand an area of about 1 inch on both sides the top and bottom of the gap. Pop any dents out of the aluminum siding by first drilling a 1 8 inch hole in the center of the dent with a power drill.

Sand the excess foam insulation to level it with the rest of the insulation. You need to fill any cracks and holes here as well. Take the x acto knife and cut out the portion of the aluminum siding that contains the large hole. Clean the holes thoroughly to ensure the metal can bond properly with the primer you will use.

Dampen a clean cloth with water and 1 2 tsp. Most of the time you can also use mortar caulk and epoxy filler to solve this problem. The less you have to cut the better. Use expanding foam insulation on it and let dry.

Then apply another bead of silicone around the outside of the hole. Then use a clean damp cloth and a little liquid soap to clean the edges. Start with a little sanding to get the rust and corrosion off. For extra protection you can use two layers.

Cut a piece out that is larger than the hole. Attach a washer to the end of a 1 inch self tapping screw and then insert the screw into the drilled hole. Wash the damaged areas with the soapy cloth to remove dirt and grime. When it is dry fill the holes with waterproof caulk.

This is a low cost quick yet effective fix. Grab the washer with pliers and pull to remove the dent.
