Paint 'Feature'

[Alex H]

Anyone any idea as to what the problem is here?

Bike is 2010 Dawes Galaxy, never used in the wet and always stored in a dry barn, so I'm thinking it's not rust.

The paint is intact and not flaking.

It's the down tube and the lines start at 'guide' for the gear cable.

It's looking as if it's under the paint which I think would have shown earlier.possibly from new but.
Has the bike been near brake fluid or anything in the barn.

To be honest, I never look at that bit very much, so it could have been there for ever

Just propped up against the wall (cleanest side) in the barn

Looks like a scar. Jesus, is that bike real?!?

But seriously, I'd have a look at the threads for that cable guide. I don't know if that screws into the frame itself but that whole thing with steel / alloy contact isn't always fun in humid conditions.

Being as it's the downtube.Is it possible that some contaminant used in agriculture (maintainance wise) has dropped onto the frame and run down in two tracks thus bubbling the paint.

It' a bit like a whodunit we have the murder but no suspects yet.

Thats been caused by an external influenced, maybe something dropped or dribbled on the paint. As well as the paint it's affected the Dawes decal too.

I would say rust, starting from the cable guide hole. I have legs like that all over the roof of the Mazda they all start from stone chips.

I've never known rust to spread like that. I'd go for something that has attacked the paint from the outside.

I have been spraying for too many years and have seen it often, as I said it is over the roof of my current car, also on parts of my turbo bike. I accept of course I could be wrong but I would put a fiver on scrape that paint off and there will be rust.

 

[Drago]

That's plausible, makes sense. Is @Alex H brave enough to scratch a little bit away to see what lies beneath?

Yes, it looks like its rusting from the inside out.

I'll let you know, if I try it.

I have the same on a steel frame that I have just taken back to bare metal. The frame is covered in in these 'snail trails', some which weren't visible when painted. Its rust, unfortunately
