Sanded back the bit around the door strike plate to repair the rust and respray. Never sprayed anything in my life but it's been a good learning experience. Treated with Bilt Hamber Deox before priming and spraying base coat. It looked really clean but once I put the lacquer on, it did look a bit more messy - mainly because the space is really hard to get even coverage in - lots of right angles and nooks and crannies.
I'll cut and polish tomorrow though, and it's out of sight, so the important thing is just sealing it with paint.
Went to treat a few spots of lacquer peel and the paint is waffer fin everywhere. It's peeling where I had a crash repair nearly ten years ago, and it's like they just gave it one coat before pushing it out the door. Really shoddy work. No wonder they went bust.
