Hi all,
Today I was having a look at my 1993 M Trax 400, with a view to deciding whether it would be worth restoring / rebuilding it. Aside from plenty of rust on the steel tubes, I noted a number of raised ripples in/under the paint. I'm pretty sure they weren't there last time I used this frame (1997), and they don't look like cracks in the frame (to my naive eyes), so I'd like to ask here (if it's not too off-topic) if any of the seasoned retro-bikers have ever encountered these features, and what they are (and what they mean). To help, I've uploaded a photo of one of the ripples, which is found on the (steel) seat tube. Any advice would be much appreciated by this novice retorbiker.

I guess rust UNDER the paint is pretty bad, then.
