: Hi All It has been awhile.... I looked at my kayak the other day and found
: the magnets on the hatches are rusted really bad, one just disappeared
: into nothing. I did fiber glass over them. So I had an idea what if I mix
: zinc powder in the epoxy and refiberglass over the new magnects with this.
: Do you think this will help? Thanks Joe

If they rusted they got wet. I've found it easy to sand through the glass over them if you're not careful. And make sure the underside is sealed too.

Replace them and make sure they are sealed and they'll be just fine.
