The most common materials used in RV construction are wood, aluminum, or steel. The smaller-sized motorhomes are mostly built using wood, but this material has a weakness in the form of termites. You can’t expect them to last a lifetime, which is why wooden trailers are quite rare nowadays.
On the other hand, steel is strong and has no apparent weakness except corrosion, but it is too heavy and adds a lot of weight to the structure. It is unfeasible; hence not many manufacturers use it for an RV’s frame.
The most common material nowadays is aluminum, which companies use to build motorhomes. It is lightweight and sturdy enough to support the RV on its weight. However, aluminum, wood, or steel are only used in the frame’s construction. The outer body of an RV is made of Fiberglass, which is extremely lightweight and moldable.
However, fiberglass material is prone to damage, as it cannot withstand too much force or the sun’s radiation. Sometimes it bends out of shape, but it can also break into pieces on impact. When that happens, you must repair the RV at the first possible convenience.
How To Repair Small Cracks?
However, there is a drawback with this quick and easy fix. The fiberglass Bondo filler doesn’t work too well when you apply it to a large area. The fiberglass constantly shrinks at colder temperatures, and then cracks start to appear on the edge of the space where you apply the filler. Subsequently, water starts to seep in, and more unnecessary damage occurs.
Voila! You are done!
Now, you must be wondering, what do I have to do for a large affected area?
How to Repair a Large Damage Area?
