I noticed the wheel arches were starting to rust slightly under the plastic spats so I pulled them all off to get a proper look at the damage.
Its not good....
They are rotting away underneath and even starting to create holes in a couple of my wings!

Whats the best thing to sort it out? I dont have access to a welder so to get any wleding would probably cost a fortune....
Could I cut the lips off that hold the spats with an angle grinder, treat any remaining rust then fibreglass over the holes?
