Right, have a week off work this week so decided to tackle some of the rust on the car!
I began today with what looked like the smallest and therefore the easiest bit...oh how I was wrong!
It started off a little bubble on the surface, so I poked around a little bit and it turned into this:
I could see that it went behind the wheel arch trim, so that along with the side skirt trim came off to reveal (excuse the crappy camera phone images):
Next was removing the trim inside the wheel arch, which revealed a
massive pile of earth! How there was that much dirt in such a small space I have no idea
Next was to grind all the rust away so it was all bare metal, as you can see there wasn't much metal left!!
Once the rust was removed I used some metal mesh as a base for the body filler that was going to make up the new part of the wing. (Again excuse the blurry pic)
Next stage was to build the filler up using a couple of layers so it was slightly above the level of the existing paint.
Then came the tricky stage of sanding down so it was flush. I started off using 40 grit paper and gradually worked my way up to 1200 grit wet and dry. I was very pleased with the result.
Finally gave the area a quick coat of primer, ready to be tackled again in the morning!
I'm happy with the result so far, bearing in mind a lot of where the rust was is going to be covered back up by trim!
