What....would be wrong if I......

Why couldn't I put silicon sealer on my coil cover to keep dirt out????

You can put it on and most likely just attract a dirty appearance around the edge of your coil, but no big deal. It should keep the dirt out. I just prefer not to use a coil covers all together...case of trapped dirt and minerals eliminated. You would have to be pretty rough on a coil to wear through or damage it to any degree other than normal scratches and discoloration.

Nothing wrong at all. It is very common. Recommendations:

Wipe everything down with alcohol
Use clear silicon
apply a bit of pressure to the coil and cover until the silicon sets up
use a liberal amount of silicon
don't forget to seal the inside hole, if your coil has one

There is an RV silicone that doesn't attract the dirt and get the dirty look Mike mentioned.

Why not just take the coil cover off periodically and wash and clean any debris out? I know some spoke coils are very hard to remove with out chipping or breaking them and some other covers are so loose they fall off themselves....maybe I just answered my own question But most coil covers are fairly easy to remove and replace; and once you clean them you are positive that no minerals, dirt and debris are in there. Plus once you seal that cover on; your buddy cannot slip a penny in while your not looking and watch you go crazy trying to figure out what's wrong

The silicon myth,,, From yrs of person experience I can say silicon is probably the absolute worse sealant known to mankind. I have seen first hand how well it seals,,, it doesn't! Just use black electricians tape its removeable and will seal the coil much better and be les weight and less mess trying to scrap it off each time you clean your coil.

I have several coil covers sealed with RTV silicon sealant. They've been like that for years. I've had occasion to remove a cover or two over the years, and can assure you that they were pristine inside. There's no need to scrape the silicon off since the whole purpose of putting there in the first place is to avoid having to remove the cover to clean the coil and cover.

I put silicone sealant on all my coil covers for years... and guess what. After use of my detectors in the field THEY ALL HAD GOT BLACK SAND IN ALL OF THEM. I could not figure that out how this happened. So now I use coils without covers.
