Hi all

With time on my hands I thought I would have a go at repairing a rusty wheel arch. Took time to research and buy correct parts needed, ordered correct paint (I think)

Sanded all the rust away, filled, primed, painted and clear coated. Left for a few days used at/dry sandpaper 1500 then 2000, then 3000. Buffed and ended up with the end product below.

What did I do wrong?

Is the Paint the correct colour, gave Halfords the correct code, but did they supply correct paint?

Please help. How can I rectify this?
