done mine on the weekend and only found a tiny bit of rust which was good [ allthough the previous owner of mine was from wimbledon so may never have seen any mud ] while i was at it i removed the front liner as well its supriseing the amount of hidden voids there are on an l322 , then i sprayed inside the arches and behind the cill trim with waxoil before refitting  2004 4.4 v8 vogue se

After receiving approval for the tailgate, my FF finally goes in on Monday for the new panel to be painted/fitted. Existing trim/screen etc gets refitted, but new screen seal and upper badges.

As part of the same job, the bodyshop are kindly going to sort out the very minor spot of rust on the inner edge of the rear wheel arch and remove the rear liners to inspect and protect anything else that's going on under there.

Hope they make a decent job!

Just thought I'd post an update on this....

New tailgate now fitted and underside of rear arches re-painted. Very pleased indeed. The friendly folk at the bodyshop also gave the full car a machine polish so it was looking lovely for all of ten minutes before I drove home on the salted and slushy roads.
