Got a bit of rust needs sorting

[Turk]

Most paint specialists will advise, if they're honest,  that a rub down, primer and spray job will look fine for a year at most before the rust appears again.

Only permanent way to cure a rust problem is to cut out/replace the corroded area.

I know it won't stop it, but it might slow it down if you give the rusted area a few coats of rust convertor.

Yep, there are various treatments available, but nothing that will permanently cure the problem.

Before you go and rip the rear wing off, if you've the time you could try the following:

1. Strip the bumper, rear light and gas filler off the car.
2. Rub down the offending area until bare metal.(will probably still be pitted).
3. Apply a coat or 3 of kurust or similar and leave it to do its thing.
4. Lightly rub down what's left until reasonably smooth.
5. Mix up some 2 part epoxy. I'd use West Systems 105 resin/205 hardener, with 406 colloidal silica to thicken slightly.
6. Spread this thinly and evenly into the area around the gas filler hole. Use a bit of pressure to ensure that all the pitting in the metal is filled.
7. Once fully cured, rub down until smooth/blended with surrounding area.
8. If needed, a light skim of filler, then primer.
9. Pop it down to a known body shop for the top coat/s.

That should see the rust held at bay for the life of the car. The idea is that the metal can't oxidise without oxygen, so the epoxy mix should seal the bare metal beneath the paint, keeping the air off. Also probably best to do the inside at the same time, (although as hidden, finish can be a bit rougher, just don't tell the perfectionists ).

Yep - the clues in the OPs details at the top (+lpg)

Yes it is an LPG filler, i presume when they fitted the LPG kit (years ago) they didn't protect the metal where they cut the hole for the filler hence the corrosion...
Thanks for that Taxi Al, i'll have a go at that

Just a thought, is the rear wing a replaceable item???

It is....but a HUGE job and can't be done easily. Specialist body shop would be strongly advised I believe!

Reaer quarter on my estate was a weeks work. I would allow at least 10 days for a saloon, as there is a bit more to strip out and the rear window has to be removed. (probably best to budget for a new screen).

Best places to look for new panels are either ebay or carpartsconnexion, just bear in mind that pre and post facelift saloons have different shape light clusters!
