Over two decades ago, HBC System developed and patented an innovative technique for repairing dents and scratches on caravans and mobile homes. Since then, we have consistently improved and perfected the process for repairing caravans.
In the following sections, we will explain more about panel types, how to assess damage correctly, our repair tools, and the repair process. We will also provide templates for comparing and estimating the cost and savings of repairing a caravan panel versus replacing it.
Technical structure
Most caravans, motorhomes or trailers feature panels made from a sandwich design with a layer of hard plastic or wood as the innermost layer, an insulating foam panel in the middle and a textured aluminum plate as the outer layer.
Aluminum panels with structure?
The primary task of the structure is to make the aluminum sheet more resistant to shocks and to compensate for minor irregularities.
The different structure types
There are currently 4 common types of structures on the market. Each structure has their own properties and must be processed accordingly and requires the use of different tools.

How the dent repair system works
With the specialist repair process an exact copy of the surface design or pattern is created from the undamaged part of the panel using the patented vacuum tool, templates, and mouldmaker. The mould is then transferred to the damaged area where the special E-Filler is injected, leaving a surface structure that corresponds exactly to the original panel. After the material hardens the borders are sanded and the whole repair area is powder blasted using a specialist granulate E-Powder. The repair area can then be primed and painted.
