Typical old car problem - the rubber strips that protect seam edges have fatigued, and don't want to hold on to the seams anymore. Anyone have some hot tips for fixing this, or is the only solution to buy new strips?

Any form of a flexible adhesive should work just fine
First thought is clear silicone
You could try some clips commonly used on British cars to retain the door seals.

I believe I've found the product also, it's known as pinchweld https://www.clarkrubber.com.au/products/37675-universal-pinchweld-14mm-x-7mm
Big +1 on the clear silicone. Work with it every day . Once you leave it for 24 hours it's extremely good . Just a couple of days ago fixed a pair of sunnies with it . But car wise it's great .
They have a metal insert in them, you can crimp them with pliers so they are a tight fit.
