Any of you guys caulk your coil covers? ...Here's what I did...:cool:

[Horsesoldier]

I used to use electrical zip ties so that I could take the cover off to clean it.

Here's what it would look like after just one spin.

Here's what I found at Lowe's

Here's what it looks like afterwards.

It makes for a much neater job than regular silicone. I've been on several spins since with no problems. Just thought I'd share.

Yo Soldier;
Like you, I used to zip-tie my cover and clean it after a spin but once when I inspected it at mid-spin I discovered LOTS of sand so... Once again like you I hit the ole Tornado with some RTV sealant around the cover edge thinking to my self "That'll Fix Ya". Now it may have kept her good for a while but Max put the creeping doubt of it leaking into my head so... upon inspection after numerous spins I found that leakage had occurred. So All that to say this. I bought myself several tubes of Lock-Tite brand Marine Epoxy (Like Max) and before my next spin I will have liberally coated the lower half of the coil and put all this out of mind until at least this time NEXT year.

... is that Epoxy painted directly on the bottom of the coil, not the coil cover and then you run the detector without the coil cover.

if u go a lot, u will need two coats and a 3rd coat like every spring

here is my new excal and cibola

Does the cover impede the signal?

 

[Mike (Virginia Beach)]

That IS the procedure. And no, it does not impede the signal. Not if you use the Loctite Marine Epoxy shown. Other compounds may or may not have similar results. I did this on my Fisher CZ-70 10.5" coil and it worked very well. On my Excal I actually used RTV black silcone sealant and RTV'd the cover onto it. Haven't had a problem. If I ever have to re-do it I will probably do the Marine Epoxy thing to that too.

Well therin lies the rub with MY method...check it??? I did such a fine job of RTV sealing the thing that I doubt I would be able to easily get it off. And if I did, it would be a tough job to prep it again for re-application. So it's a semi-permanent type of thing. But I know what the machine acts like when it gets "salt crazy", so if that happens then I WILL re-do it. On the plus side, I've had it like this since the middle of last summer and it's good to go. And as long as it is, there's no need to re-do it like you might have to with the Loctite. I think both are good methods with their strengths and weaknesses. Main point everybody should get is that if you use a coil cover, it needs to be SEALED and sealed GOOD. And if you don't, you need to protect it or it will eventually split.

Nah, whatever they had at Advance is what I got. RTV black looks good.

 

[Joe G]

Got that idea from Max 2 years ago and it works great. I put on one thick coat of the marine epoxy and then another coat of clear (stuff I used for saltwater flies). I don't go to the beach nearly as often as most guys here, but it's held up nicely after a lot of dirt and sand diggin'. I tried the silicone a couple of times but the epoxy works best.
