Rust spots

I just went out to clean my motorhome and discovered it is covered in tiny rust spots. They were'nt there in December when I last washed the van. The van is a 2014 and I bought it from a dealer one year ago. Any advice welcome. Thanks

Somebody has been cutting steel nearby with angle grinder?

Sometimes they can be caused by a drill or grinder previously being used at or near the site where the rust spots have appeared. Where very hot tiny pieces of swarf are thrown from the drill/grinder onto an unprotected surface.

Can you give any more info as to where they are situated ?  A/s gave a poor record of sweeping up swarf from cutting holes in their van conversion range which turn to rust welding themselves to the paint finish but as you have a coach built this may be different. Has anyone been welding cutting or grinding metal close to your van as I have seen untold damage done to the paint finish on one vehicle by someone grinding metal 20 feet away and the wind carrying minute particles of metal unseen which stuck and promptly rusted on to the unfortunate vehicle. Only became apparent a few days later when rust spots were seen all over panels and windows!

Mostly on passenger side and rear rear of vehicle. All over. I fell and could my drive home from France in January and the insurance company stored it for 3 weeks and repatriated it. Don't know if it was there.

Any idea where I would stand with my insurance. But worried that I've got a van that's worth nothing.

In that case I would be contacting your insurance company if you think it happened in their care. First I would try a little fine cutting compound to see if you can gently remove the  marks in an inconspicuous spot.Dont go full commando with heavy compounds , a light restorative polish will do. Anything more and you will remove significant paint and why should you if not responsible for the damage . In that case try contacting insurance as if you say done in their care , they should restore to former condition.

Friend thinks it might just be atmospheric pollution and tree sap, in which case it just needs a proper wash and polish. Will get it checked out.

Excuse me for being thick, but am I right in assuming the Nuveo rear is fibreglass. I ask because on a Topaz we once owned the high roof suffered from what looked like rust spots all over, they were pimples.

I had a Symphony that got the roof covered with tiny black/brown spots that cleaned off .  After googling such a problem, it was thought to be atmospheric pollution.

Could be industrial fall out it used to be a big problem in Sheffield ,when we had steel works

I spoke to a caravan cleaner today and he's coming tomorrow with a power washer. He didn't seem to think it was rust. Thank goodness

Power washer! 

Watch out for your seals and decals.

Anyone turning a power washer on my coachbuilt van and I would chase them for their lives! Do  not let them anywhere near seals mastic decals light units etc  This issue needs care to resolve not the equivalent of a sledge hammer !

Those were my exact words to Peugeot Main dealer when they said " we always clean your van after a service" No way, having just seen them cleaning an Open Reach van with the most powerful jet wash I had ever seen.

Yes I always take the van in spotless for MOT  and they always try to give it a courtesy jet wash !  Don't like being asked if they let their guide dog carry the hose......

Same here wouldn't let a pressure washer anywhere near our van.

Took Lady G's Z4 to BMW for an MOT a few years back, it failed on a light bulb, mechanic A removed the old one and went to get a replacement. Mechanic B then pressure washed the car ( despite my saying not to) and filled the headlight unit with water!

The car is now serviced by a classic car specialist company, never been near the BMW dealer since.

Back on thread of course we all know GRP doesn't rust so it isn't that Paddington. If it is on the metal part rust comes from the inside out so is easy to identify. As others have said almost certainly just pollution of some type.
