When replacing or repairing wheel fender skirts while doing RV body repair, it is a good idea to get parts that were made for your recreational vehicle. In some cases, you can even replace all of them with new skirting that matches your frame. Most skirting on RV vehicles are held in by securing bolts or rivets, and can be easily removed and replaced. The main concern in this situation is to ensure that the shape, and the mold of the new skirts match your wheel hubs. They come in several designs for protection and effect, short to show your wheels, and long skirting to cover them up. If your fender is simply bent or has a tear in it, you can do a repair without replacing the entire panel, which can be very cost effective.
Step 1 - Remove the Skirting
The first part in the RV body repair process it to remove your part from the vehicle. Once you have the skirting off you will be able to work with it without much problem. For skirting that is riveted to the side of the vehicle, you can bore out these rivets with a drill and then remount them with new rivets once you're finished.
Step 2 - Rework the Skirt Surface
The next step in the RV body repair process, is to determine what type of material your skirt is made from. This will decide which repair materials you are going to need from the materials list, and the method you will use to apply it. The first thing to do is to take sandpaper and rough up the area around the crack or split.
Step 3 - Starting a Patch
Regardless of the materials you are using for your RV body repair, you will need to rough the surface around the break or crack. Once this is done you can use your epoxy, or bonding materials to cover area around the hole. This is so the mesh will stick into place once it is applied, which will be the base of your repair. Take your mesh and cut it approximately 1 to 2 inches wider than the crack or break. So the patch material should be connected to the skirt a short distance from the break, all the way around the opening.
Step 4 - Apply the patch in Layers
As you continue your patching of the RV body repair, you will want to apply layers to the skirting until the hole is no longer visible. Try not to glob this on and try to apply it as evenly as possible, to prevent bubbling of the surface. You will want to let this dry, and then sand the material down into the proper curve and shape of the skirt. This is the reason behind not applying it too heavily, to avoid too much sanding in the end to even up the skirts design.
