Scott bars had it?

I'd love to keep these, and spray up. But?

If it was mine, I would strip and polish or paint, but... I don't weigh a lot and I rarely break things.

Surface corrosion is different to fatigue - but any 30 year old lightweight aluminium bar is beyond its life expectancy.
How much they've been used probably has a bigger effect than corrosion, but is sometimes less obvious.

Really? Most of the bikes on this site have bars over 30 years old. Does that mean we're all risking it? Genuine question, not trying to catch you out

Depends on weight, alloy, level of use, design and corrosion.

Any 30 year old bar will be weaker than when it was new, but the difference might be insignificant.

Try asking the manufacturer if the bar is still safe to use as designed

Few retrobikes are used to their original limits though - but I accept my 30yo mtb is more likely to break than my newer stuff.

What made me raise the issue though is that in my experience, lightweight handlebars with the sharp-edged shim in the middle, like these pictured, can be prone to sudden failure at that exact point

LOL, I have a set of mint Drop-Ins on one of my builds. They take a lot of bar tape.
