Rear arch rust repair

Recommended Posts

There's a small patch of rust on one of the rear arches. It looks to have started at the fixing point for the plastic trim where there is a hole in the panel.

I attach a picture, although there's not much to see.

I have not yet removed the arch liner etc to get a good look.

Has anyone dealt with this before? I'm expecting to create a hole in the panel when all the rust is removed.

You'd need to go a little further than just removing the hockey or wheel house shield as you need to get behind the wheel housing to feel what is going on. You'd be best removing the cabin air vent (4 bolts) which is located behind the wheel housing plastic shield (3 bolts). You will then be able to feel behind the corrosion to find out if the metal inside is corroded or smooth. If its smooth then its easier to sort external rust which can be ground back to metal and then the hole filled with a fibre patch from behind and filler or patched with fresh metal if its large enough to warrant that.
