colesl4w Posted December 28, 2016 Share Posted December 28, 2016 Hi all, Hope you all had a great Christmas break. I have an area of bubbling on my rear driver side arch, not far from the fuel flap. It has been slowly getting worse, and originally I wasn't really concerned as I thought it would be a simple matter of getting a small area cut out, patched up and painted. Now that I have read into it, I see that the rear arches on the Z have two layers, and therefore once rust sets in, repairs may only last a few months before rust shows up again. Has anyone successfully repaired rust spots on their rear arches, and had the rust stay away permanently? If so, what method was used? I do love this car but don't fancy starting a losing battle with rust if any fixes are only temporary! Would love to hear your experiences. Thanks!

Rocket_Rabbit Posted December 28, 2016 Share Posted December 28, 2016 Same on all cars really. Wash regularly, clean the inner arch lips, and use cavity wax (Waxoyl, Dinitrol etc) through the drain holes. However, your repaired arch will not last as long as the OEM job because the techniques Nissan/car makers use are very good indeed. Quote Link to comment Share on other sites More sharing options...
leonk Posted December 28, 2016 Share Posted December 28, 2016 (edited) Cut out the rusted piece, blast area to bare metal, spray with zinc weld through primer, weld in repair and paint. Then, and this is the important bit, bladder the inside with Dinitrol, Dynax or similar hoping it will seep into the tight gap between the inner and outer wing. The problem with welding a new bit in, is that the heat burns off any protective coating between the two panels. Added to this, welded steel seems to rust faster. Someone technical will tell me why hopefully. Hope that all makes sense. If you own an old JAAAAAG you have to become an expert at keeping the "patina" at bay. There are some pics in the build thread of me cutting out and repairing a rear arch section. I'd post pics but my photobucket account has been taken over by dawned ads and pop ups!

Mopedmark Posted December 28, 2016 Share Posted December 28, 2016 Yep the only way is to cut it out I have repaired my driver side but it's coming back, I'm cutting the bas#ard out next time Quote Link to comment Share on other sites More sharing options...

BSCZ Posted January 6, 2017 Share Posted January 6, 2017 I had exactly the same problem, in the same area - rear wing by the filler cap. Seems like a common issue on some of the older Zeds. Got a number of quotes from local bodyshops - around £250 for a quick fix, or £500 to do it properly, as described above - cut out, treat and weld in new metal, spray and seal. On the basis of recommendations and experience from others with the same issue, I went for the latter, more expensive option as I wanted a long term solution. This was last summer, the bodyshop did a great job and I've not had any issues since. I'm based in Southampton and used the bodyshop Pitt-Stop Garage. 1 Quote Link to comment Share on other sites More sharing options...
