Cleaned the new motor the other day get some of the winter grime off for a day or 2. Came across these couple of paintwork chips on the roof. Have I got to worry about them with the colour? Look almost like rust. Anything I can do to treat? Cheers20250117_091142.jpg20250117_091147.jpg

They are down to bare steel, as you can see.

If these are not fully ground out to remove the rust and correctly treated, you will end up with a hole in your roof.

You can DIY but results will be likely terrible (at least, if I did this job they would be terrible).

Based on my experience:

DIY job - including removal of rust and then applying undercoat - will be good enough to prevent further rusting. The surface fill and paint match could be reasonably decent to the extent that it won't be noticed from a distance.

Smart repairers will do a much better job - the repair will be almost noticeable, other than when looking at it up close. In other words, most probably only someone checking-over the paintwork will notice it.

For a seamless 'like new' repair, only a body shop will do.

In summary, it all depends on what you are trying to achieve, and how much you are willing to spend.
 
Polish out rust, treat any remaining rust with chemical, prime, build up to slightly above the surface level with layers of colour and clear lacquer......cut back flush with compound. Job should be just about invisible. Using a body shop for a stone chip seems excessive to me. Especially as you could go out and get another chip the next day! Stones chips just happen and a pretty much unavoidable. Pity I have not got a pic of my old 209 bonnet.......more chips than paint for the first foot as it spent its life on the motorway before I bought it! That I did get resprayed.....but none of the chips rusted like that....just stayed white/grey due to being galvanised.

Yes, I think I was a bit quick and distracted whilst burning toast this morning 😝


I should have said, get this professionally repaired if you want a really good job (including smart / chip repair).

DIY is possible, but if I did it it would stand out like a sore thumb.
 
Thanks for all the replies. I've had plenty of stone chips in my time but not seen one rust like this before hence the concern. Is there a particular treatment chemical I should be specifying it be treated with?

I have never had a problem using a spot of Kurust, then build up with paint and lacquer once it is dry.
 
Personally, I’d sub it out to a mobile chip specialist like Chipsaway. They’re cheap, come to you, and have a specialist’s expertise and all the right materials. “Other brands are available”

Had this reply today from a local chip repair guy

With that being rust the only way of properly sorting it out is to sand it all off treat then paint the roof. That's no something I can do mobile.
The only thing I could do is treat what I can see then touch it up which would be the exact same thing you could do with hamerite krust. And a touch up paint. The minimum for me to come out to a job is £100 which is not worth it really for that. Just trying to be honest and give my best advice possible
 
Spoke to another guy said no good for him as the paint these smart guys use is water based. Said to get some t cut, polish out the rust, then repair with proper solvent paint. I asked about the rust protector and he seemed to think the paint would be just as good. I suppose he's assuming you t cut the surface rust out.
 
Not sure to be honest...could well be. Certainly smells like it.
But not sure what that has to do with why he won't do it.
 
Best video I've seen setting out a quality chip repair is by Larry from Ammo NYC.

He uses hole punched wet and dry sanding paper glued to the eraser on the end of cheap pencils to get great control.

If DIYing, I'd give this method a try. Maybe given how rusted the chip is on your car, you might need to try a coarser grit to really get all of the corrosion removed. But the principles are the same.

The results from this might not be perfect if we try it, but I think it gives the best chance of giving a reasonable result.

I don't know what method quick chip repair outfits use to get the job done in half an hour or whatever they do for 100 quid.

I have had a couple of very good smart repairs carried out on cars.

It certainly isn't done in half an hour for £100.
 
Well I've phoned a couple now and they've both said similar. I've been trying to phone more 1 man band type outfits. Not for cheapness but just so I get honest advice rather than a corporate franchise who will do it regardless
 
Try it yourself with advice given on here. If your not happy, then Chipsaway or Bodyshop. You have nothing to loose except for less than a tenner for supplies.:thumb: Can't be that bad if you have never noticed it before
 
Been watching a few Youtube vids on chip repair.
Has anyone seen (and got any links) to good videos on this they've found that might help the Op?
Obviously Larry Kosilla takes it to the next level. Is there anything less involved that anyone can recommend?
 
Seen this Mirka mini paint plane for removing proud, excess paint after chip filling.

Seems expensive at £30, but after watching this video, I'm tempted to get one and tackle some of the small chips on the bonnet!
Wet sanding proud chips had been putting me off, but this thing looks a lot easier to use.
