I have to repair some body panels so I read some topics concerning that. Some people recommend to use epoxy resin because it sticks better but others polyester resin which is much cheaper. Next I asked some experts who make galssfibre body panels and spoilers for cars and all of them use polyester. I have just phoned a resin expert for some advice. He told me always use the same material. Epoxy for epoxy and polyester for polyester panels. If you have a polyester panel then polyester resin sticks better than epoxy because chemical bonding connection can set during repairing between polyester materials. So now I am looking for the material of the Murena bodypanels. If I know well it is made of polyester. And I found that: http://en.wikipedia.org/wiki/Sheet_moulding_compoundAm I right?

Some body panels have been repaired, the bumpers and the front wheel arches. My father used to work with resins and fiber glass, he repaired aircrafts, helicopter rotor blades and once a boat so he can help me. After sanding and cleaning the damage, we applied epoxy resin and fiber glass to reinforce the structure. At critical areas we applied two or three layers. We also used fiber glass kit (green material) to fill the surface and replace the missing parts. Then it was also covered by fiber glass and resin. Sometimes we used a piece of foil to prevent weeping of the resin at vertical parts. It is easy to remove after bonding. I have also posted some photos of the rear bumper: http://www.matrasport.dk/forum/index.php/topic,2301.15.htmlI found a surprise. The front bumper of the car was changed in the past because it was silver originally (the car was corall). When I asked the seller he wrote me the car had never been damaged... ![Tongue](http://www.matrasport.dk/forum/Smileys/default/tongue.gif) Fortunately the chassis is ok so it could not be serious. I will remove the side sills tomorrow they are in bad condition. It will be tricky to repair them...
