What silicon can i use to seal my wheels?

Hey guys, my 3 piece wheels need to be resealed because they are leaking from the nuts/bolts. I need to know what kind of silicon do i need to buy. also where too if possible. ohh and any tips besides the silicon?
im not sure if i could just use regular bathroom silicon.
thanks

use black rtv sealant, run a small bead on both mounting surfaces and smooth out with your finger (covering the whole surface area with thin sealant).  assemble wheels in a crossed tightening pattern, and lay down a bead where the pieces meet, smoothing with your finger (gloves help).  wait 24 hours, do it again, wait 24 hours, mount tires

I assemble the wheels DRY after carefully scuffing the mating surfaces with Scotchbrite and cleaning them with acetone. Preparation is key.

Applying sealant first can make it challenging to get the parts all in parallel with each other and it makes a mess of the bolt threads when you install them. It makes a big freaking mess in general... wear an old shirt.

I don't use silicone (I use a proprietary sealant made by Permatex that is not available retail) as I have found Silicone doens't have the best adhesion properties. We used bulk clear Silicone at HRE (I believe they still do); as long as it's 100% RTV silicone you should be good. I prefer the clear stuff because its easier to inspect if for air bubbles and defects. 

Try to keep the sealant within the "crack" (split) area of the rim halves - less is more. If you get too much extra on the barrels it can actually peel up when you mount or dismount the tires. I have a machine that rotates the assembled wheel and I use an electric caulking gun to lay out a nice bead. Most people don't have one of these machines.... otherwise you can use blue painter's tape to tape off the rim barrels on either side of the split if you want an ultra-clean job; just smooth out the silicone with your finger and carefully remove the tape (with any excess silicone on it) immediately after smoothing it all out. If you have access to a tire balancer, I would recommend installing the wheel on the balancer and spinning the wheel by hand SLOWLY while applying the sealant. Or, you can just roll the wheel on the garage floor and follow it with the caulking gun ;)

One other note: wear disposable gloves. Getting this stuff on your fingers sucks.

This is the compressed air powered gun similar to my cordless gun. I just like the name:

thanks for the tips guys.
is permatex brand rtv okay??

Permatex is great stuff. They actually manufacture the sealant that I use, although it is not silicone-based.

Great info!

Care to do a write up since you are having to do this! Take pics for us

damn i just couldnt find any permatex at walmart.
so i picked up some general purpose silicon.
hope it works well enough

I used the GE silicone II window and soor sealant, found in HomeDepot or Lowes. Try to get the clear one for cleaner result.

 I used the same silicone on my rim that leaked, got it at Walmart

Good stuff. Subscribed for later use

last i heard HRE preferred Dow Corning 733, which is available by the case.  iirc there's a guy on E46 fanatics selling some since he actually went and bought a case.

good info I just took the faces off my wheels too

I bought regular ol' silicon at walmart for 2 bucks and it works fine.
i sealed all my wheels and none are leaking....yet :biggthumpup:
