I've already got lights on the roof of my car and wired (came with the car). My question is: The guy drilled a hole in the roof and ran it out of sight inside down the a piller...since it's already that way, I'd like to make sure the hole is sealed. What is the best way to do this. going to use a rubber grommet(spelling) so the wires won't rub thru and...not sure...any ideas?? or someone that has run the wiring thru the roof like mine?? affraid rain is on its way :-\

Seal it with fast-cure 5200 marine adhesive sealant. That stuff is the bomb. It will not leak, and it will keep the wires from rubbing.

just use silicone/caulking from a tube or spray foam. That will seal it good

My brother told me to just use silicone but then he's never put wiring thru the body of a vehical so I figured if anyone knew what to do someone here would know.

I ran my wires out between the antenna and the a pillar. I used romex house wiring because the stuff is really stiff and pretty strong since its solid strand wire. I used great stuff to seal the gap and just cranked the nuts down on the as tight as they'd go. I'm not down with drilling a hole in the roof.. soaking wet headliners SUCK!!!

 

Kelly is right though. They make a few different colors of it. Just becareful that stuff is sticky as hell and it WILL make a big mess.

Well I could always weld the holes and go another route but since they were already thru the roof when I got it, I'll keep it that way for now until the roof rack is done. Then I'll do it all right...so far I haven't had any leaks and was going to leave it alone until I found all the hack job of wiring the guy did...now I'm a little worried about having a wiring fire so I'm rewiring alot of stuff I found including some major wiring under the dash I found when I had the dash out...melted wiring and connecter...got the replacement wires from another soob, just gotta get it done.

if you want a little extra security, use a small piece of wiring loom where the wires pass through the roof if you dont have a grommet in combination with the silicone.

I just squirted a dab of black RTV on mine, no leaks from there... but I do have others....
