I've often been asked for a fix - and here it is, my CX-12 PowerPatch!
If your ABS cement is not the thin wicking type, you can coat the PowerPatch with thicker weld cement and move it into position before pressing against the shell. In that case hold the spring in from the outside to keep it in the right position before pressing home.
