hi   I need to replace the rear plastic wheel arch on my Scout. It got damaged by some kind grounds maintenance person where I work.   What do I need to do to replace the arch (ordered new one from Skoda)? I'm assuming that they are bonded on to the car (?) - if so what's the best product to use to clean the area and bond the new one? I've seen that there is a cleaning/bonding kit you can buy from Skoda but the cost is crazy.   Any hints and tips much
