5 and 6 should be cured, last year I changed the oil and filter, it was really low on oil for MOT and had the old stuff in. 7 and 8 my new MOT station of choice should put down to lack of use and let slide as per FSO. 1 Needs an Auto Electrician out maybe, the wrong lamps come on I seem to remember.

Can someone help? I need a picture of what the panel(s) behind both headlamps 'should' look like. I've not much to work with after removing crust held together by underseal and paint :/ The flat horizontal panel was rounded into a vertical inner wing panel with filler? Hard to explain without uploading a picture maybe but I don't have the option at the moment

It's probably factory seam sealer? Unfortunately I can't help you with what it should look like, but the good news is it doesn't appear to have been got at before from your photo. I'd start by getting rid of all that underseal (hot air gun and scraper is good for this) and see what you're dealing with. Assuming access isn't too difficult, I can't see anything there that should be that difficult to fabricate.

Took the driver-side wing off today and was admiring my nice 'solid' a pillars when a tiny flake of underseal caught my eye, anyway the admiration was short lived. It pains me to see this car in bits, it's my favourite car of the 1980s :( Anyway I guess this is... progress? Here's a better shot of the headlamp (was) panel area. I've still some stuff to remove from the engine bay. I've not even taken a grinder to it yet and I'm starting to worry! 1qs7dg.jpg

Got the near side front wing off today, had to use my Netto rotary tool to cut off a bolt, got through no less than eight cutting disks. Shite! Anyway there's more metal to work with than the other side. But gonna have to get some nice patches fabricated for both flat headlamp panels. I expect a horror story once I get the grinder to them. The near side chassis leg aint great but there's plenty to work with! 4g4uc9.jpg

So today I removed the air box to expose some more rot. It seems every hole I find has been patched previously. The repairs have been welded on and fillered over, then painted. Each repair has rotted right through. What have they done wrong? Both sides were heavily coated with various different things... I don't want to make the same mistakes.

Crikey that doesn't look so good. Not wanting to piss on your chips but I would have a good look elsewhere and see what else needs doing before you go any further. How handy are you with bending metal and sticking them together?

I'd get smashed into that with the wire wheel, get all that underseal off and see how bad it really is as you can bet there more lurking under the sealer. You might be as well trying to get a front panel for it even if it's just to chop up and use for bits to weld in.

I can't wait to take a wire wheel to it! What is stopping me is my extension reel was stolen and it's £50 that I don't have to replace it. I prefer to do all the work either in my garage or just outside of it. I could drive the Opel to almost my flat window but at the risk of annoying all 12 neighbours at once; I think I'm going to have to wait.

Okay today I took a trip to B&Q and bought a nice 45m extension cable for £39.99 happy. And took my grinder with a nice Clarke wire cup attachment (which has been excellent compared to ones I've used in the past).

Is my picture working?

 

'Fraid not. That may be just as well, as I had to look at your last pics of the inner front panel from behind the sofa :shock:.

 

Looks like you've got a job on with this one. Good luck with it as these are very handsome things.

Thanks! And I've got Benno on the case with thd pics. I've tried ten pic hosting sites. None work. It's so frustrating using a mobile phone in place of a laptop! Had a really good day on the car too and 'techology' gone and made me angry. I've been looking forward to sharing my progress! Why tinypic have banned my ip address I'll never know. All I've uploaded has been cars. *breathe out* :@

Weld in good over sized patches over the holes you find - not postage stamp patches which barely cover the hole.Put good metal in,and once its welded up,protect it as best you can with paint,and sealer ( as appropriate ) and inside any internal structures,spray waxoil,or even better plain engine oil inside to give it a good coating,which will seal it,and keep new rust from forming.I find oil is better than waxoil,as it doesn't dry out,and will seep into seams better.Get as much oil inside chassis legs,and other internal structures as you can,as a few minutes messy work saves hours of welding. I always get inside the rear wings,and get oil over the inner wheel arches - never had a car rust out with good old fashioned pickling.

Excellent, thanks for the advice. I'm wanting the best possible sealing. I'm going to seal f*ck out of it. Plenty of work to do in the mean time. The ns chassis is goosed! Ooh going to buy Hydrate80 to go on bare metal before painting etc

Did as much as I could today without being able to pull the car outside. Thanks rain. I've been working on the near side headlamp panel area. I'm worried the battery tray is going to have to come off to access the rot yot can see to the left that I couldn't get at with the grinder. Infact, there's lots I cant get the grinder at. Where can I get quality wire brushes for my rotary tool (cheapo Dremmel)? It came with one and I anhialated it in seconds. Here's the pic of progress: Amnear.jpg
