My 2015 puma has done the same, no mud behind it so it has just corroded through.

My 2008 has the same hole, have seen it on others of the same period. Assume it's a pressing defect.

A repair will be temporary, unless you want to spend more money than a new part would cost.

Body filler typically absorbs moisture. I think you can get some that pretend not to, but certainly most do.


On a dent, the area is sealed, the filler applied, and then the filler sealed.

On some corroded alloy hole, you're not going to get enough of a seal to stop the filler acting like a sponge and holding the moisture and, as has been said, accelerating the decay.


Again, live with it / live with it until you can afford to replace / do a placebo repair that won't last / do a true repair that will cost more than simply replacing (I doubt that that is possible with forum "advice" in the short to medium term)

Part of my job is finishing / refinishing alloy. I would not attempt a repair with filler.



Would something like Quicksteel two part epoxy work ? I don’t expect it will absorb moisture, could form a strong plug on the inside ( as long as good prep is undertaken ) . And with good smoothing and sanding provide a flat surface for priming and painting. Potentially using fine filler over the top once epoxy has set hard as moisture should not get through it from behind via the epoxy.

I’m not a paint expert, just putting up an idea to get your views.

As for me, as it’s the front offside wing I would get a new one, spayed to match then fit. With lots of corroless paint on inside followed by bilt hamber dynax UB. That will give you 30-40 plus years of protection.

It’s very common, it is alloy corrosion, seen it for the past thirty years in front of the rear wheel arch where damp mud lingers. It happens too at the lower edge of the rear wing where the steel support touches the wing.

I’ve got very good at Tig welding them up and blowing over the panel.
