"JB, while great stuff is only
"JB, while great stuff is only a filled adhesive, not much good for making skeg metal from nothing. If the chips are small as you describe, check to be sure you don't have any obivous cracks started. Then take a Dremel or Dotco and smooth all the rough edges of the chips and go back to boating.
If you have cracks just get it welded. There are some bolt on replacement products too for big damage. You might post a picture to let the members that are drive experts take a look. I had most of one of mine break completely off, got a new one welded on easy."
