What Type Of Caulk Is Safe For Coils?

[Michigan Badger]

I want to seal my coil cover so dirt can't get inside. What type of caulk is safe and won't eat the coil plastic?

None Badger. I used to use silicone sealant to cover the gap where the cover fits the coil. I don't anymore as it only takes a small crack in the cauke and black sand gets inside.

Have you thought about Loctite Epoxy and leave the cover off?

I USE EPOXY ON THE BOTTOM OF ALL MY COILS, THE CAULK WILL WORK FOR A SHORT TIME AND THEN IT WILL START TO LEAK AND THEN IT TAKES HOURS TO GET ALL THAT CAULK OFF,

Thanks to all.

What is this epoxy you're using? Any brand or type?

How do you guys apply it?

Is it on the coil permanently?

Thanks,

Badger

Loctite Epoxy is the product name , I have 2 new bottles of the Loctite Epoxy Marine to put on my Sov coils (WOT & 10 inch)

There isn't any metal in this paint, is there?

No....

USE SLOW SETTING EPOXY AND I USED PAINTERS TAPE AROUND THE COIL TO STOP THE EPOXY FROM RUNNING ALL OVER, TAPE INSIDE AND OUT TO MAKE A FORM I USD 2 oz ON MY PLATYPUS COIL THAT IS 8" 11", MIX THE EPOXY GOOOOOOD!!!!!!!!!!!! POUR IT ON THE COIL SMOTH IT OUT LET IT SET PEAL THE TAPE OFF GO DETECTING.

GOOD LUCK FIND LOTS OF GOODYS.

Badger....I have had the same problems with leakage in the past trying to use caulking to seal my coil cover.
I took my coils to a Rhino bed liner dealer/installer and he sprayed the bottom of my coils with Rhino coating. I first tested the material to ensure it was non conductive .....Friends have gone to the auto supply store and bought spray cans of bed liner for about $9.00 a can and used on their coils..check for conductivity before using.....this is the best solution that I have found for water,sand and salt build up between the coil and the coil cover....coating comes in a variety of colors,so you can be the first one on your block to have a multi-colored coil...

Thanks Treasure_Hunter, edgemano, rdi, and everybody for the help.

Minelab (and the others) really need to address this problem.

I hunt plowed fields and they are very dusty. Those coil covers cause too much trouble at these sites.

I used to hate Tesoros for their coil covers. I wonder how many coils get out of balance due to twisting during cover removal.

At some sites I can get by without a cover or painted coil. But, at those rocky sites an unprotected coil wouldn't last long.

I like RTI's solution even better. I'm going to find a local Rhino dealer and see what they charge to do all my coils. I will check conductivity before using and use masking tape, take them all at once and have them done at same time.

I've used a quality 100% silicone by Dow and have never had a problem. I use the clear. I've never had an issue with it cracking yet. The 100% silicone is pliable and will not crack. Someone said theirs had cracked? All I can say is they are buying some cheapo grade then.

How did you apply the silicone?

Has anyone tried 5200 marine grade sealer. That stuff is tough. I once used it to seal a boat outdrive and then went to remove it a year later.... it was so strong and well sealed I had to pry to outdrive off the boat. It even took the fiberglass with it in spots, but it will not crack and is tough and plyable

Walmart sales Liquid Nails brand clear seal.

I have it on both my excalibur detectors, Put a heavy bead inside the coil cover

And press it on the coil,And use a thin piece of card board instead of your finger to coat the outside seam.

Once you press the cover on the sealant will keep sand and dirt out,and this brand sealant does not crack

Ive had it on both beach detectors a year now, and have not had any problems

Michigan Badger, check out this thread. It'll probably help you out considerably. I used the epoxy and have not had any problems whatsoever.
