Hope everyone's enjoying the sunshine (at least it's been a lovely sunny day in London - hope it has been elsewhere too!).
I have a question about rust. My camper has some areas of rust on it but I can't afford a re-spray just yet, so what's the best interim / preventative measure to stop the rust getting any worse?
Here are some pics:



My friend who lives on a barge said the best thing to do would be to scrape off the rust, scrub down to the bare steel, then paint over - it'll look a bit patchy but at least it'll prevent the rust from spreading.
What do you think? Is it the same with vans? Is this the best thing to do or does anyone have any other suggestions?
Any advice much appreciated

Thanks all
Jess
