I drill small holes in coil cover and then put a nice coating of epoxy into the cover then press it to coil yes some will ooze out of the holes which is fine... FSA46 taught me and it lasts forever..

Loctite is THE way to go. I have a machine with a new coil that doesnt have a cover. I really go thru covers no matter the water machine. But it this case with no cover...... i thought wow over $300 for a coil.... this could be bad. But i put marine epoxy on it and thus far no ware. One coat .... the stuff spreads like peanut butter with your finger. Refresh as needed. Its nearly 4000 lbs psi holding.

You don't lose any depth... I am a scrubber when I hunt and sand is abrasive and I still have me coil cover intact after the epoxy treatment. the drill holes allow nubs to squeeze out its like a studded tire they wear down slowly..

You really dont need to cover it on thick..... its all about knowing where its wearing.... and you can see the wear. So you just dab on a bit more as it wears down. Depth loose .... well you arent talking huge.... almost everyone could make it up just by dropping their coil swing. Gets a little funny watching how some get casually take their detectors for a walk..... hey but many say its exercise.

Wow! You sure put a lot of TLC into that bottom, Clean work!

Mine over the years I just coat it and never look at it again, it looks that bad.

Hey Dew, One should note that when doing Minelab Equinox coils that there is not one coil I have seen that is not underfilled from the factory. I have seen 7 factory coils.

To explain further, the potting compound is below the frame height. When putting epoxy on, bring the low spots up to height then give the whole coil a coat.

If you keep the frame height high you risk chipping and breakage of the frame.
