Oh dear I’ve never actually seen corrosion as advanced as that in that specific area.
I’d want to take the wings off to get them sorted out and also take a look behind to see if anything more sinister is lurking. You can loosen the wing to create a gap in order to do what you suggest but I’m not sure it would resolve the issue. Others will probably know better. Whatever you go I hope it resolves it  |

There's quite a gap between the wing and the steel footwell.... I don't know if this is Galvanic corrosion?

More likely just poor paint in that location.

The OP says "Both the lower front wings".
I know there is a steel stay there behind the mudguard, which is a flat bar between the footwell and the bolt that connect the sill panel to the mudguard. But I doubt if it is galvanic corrosion, which usually is more concentrated and happens in very close proximity to the steel part. 1988 90 Hard Top, 19J Diesel Turbo, Shire Blue - Restoration ongoing 2012 90 CSW, 2.2TDCI, Santorini Black |

How dirty is it on the back of the panel? The only time I see that level of paint bubble is when there has been a clod of earth wedged up on the rear of the panel. You may find if you feel back behind it that there are holes in the aluminium

That’s what I found when it started bubbling. I purchased the vehicle in October and several months later the corrosion started. I found loads of wet mud in the sills below both doors - the previous owner used to drive down a very muddy farm track . I cleaned them out , hosed them clean and the sprayed 4 cans of acf 50 on both sides😳
I assumed it was galvanic corrosion but maybe it’s not then ..but I thought this was the way aluminium could corrode. Maybe I can just use duralec or similar for the inner side and repaint etc the outside of the wings…? The rate of corrosion has slowed or even stalled but I’d like to nail it completely. Thanks! |

Ahhh that'll be it then. Sorry mate, I was hoping I was wrong
 So now that the panel has become compromised the only real solution is a replacement panel. The corrosion will come back otherwise. |

Thats been full of wet mud or worse, the wing skin is now beyond repair I would get both wings off and check the bulkhead footwells for corrosion and get them cleaned up and painted.

Thanks for all the advice. It’s booked into Taylor’s 4 x 4 in Tattenhall in a week for re waxoyling so just waiting for a quote from them for replacing the wings.

Please please don't put any wet waxes particulary Waxoyl near any corrosion it will multiply your problems because it does nothing to prevent the rot developing and worse actually holds in moisture to accelerate the decay. You really need to either prepare any problem areas yourself or supervise the cleaning,descaling and correct treating/repainting. Also the backside of the new wingskin needs a good couple of coats of something like Buzzweld WAR before fitting. Unfortunatley most bodyshops dont like corrosion repairs so tend to cover the area in some type of black bitumen or wax based product. I would certainly want to view the before and after prep before any wings or product is applied.
It is a good idea to fit the Gwynn Lewis mudshields after rectification work. |

Good look - I hope all works out well and doesn’t break the bank

If the farm track has animal crap down it and that was thrown up inside it's probably the cause. As bad as salt.
