Dirt Disciple
Hi guys, just picked a 1996 Cannondale frame. The paint is in 90% good shape. But there is sadly quite a bit of bubbling in certain areas on the frame.
Please see images attached.
I've tried to read up as much as poss before coming on here about the best thing to do with this, but only really managed to find reddit forums. So thought i would ask on here as i know some of you guys are absolute gurus.
I've read that you should rub down all the bubbling paint and remove the aluminum oxide and then either primer these areas or polish them.
And i did find this post:

Would you agree this is best course of action?
I removed the paint from the worst effected part of the frame on the rear stay. And found quite a deep hole it not sure if this is pitting from corrosion or if it got punctured and that's what caused the corrosion the hole doesn't go right through to the inside of the stay. But is prob at least 2mm deep. Would you be worried about this and if effecting the structure of the frame?
Finally is there anything you can fill this hole in with to try and bring back the strength?
Thanks to anyone that replies.
