What sealant used to reassemble 3 piece wheels? Where to buy extra fasteners?

[FRC#44]

Bought set of used three piece HRE wheels that were disassembled. Required bead blasting and polishing to be decent. Problem is I do not know what kind of sealant is used between the pieces when I reassemble them? Also want to replace a couple of the metric allen bolts and nuts. Any idea of where to get them for a reasonable price.

For those that may be interested, found following on the net:

Two & Three piece modular wheels require periodic maintenance. You'll want to work out your own maintenance schedule, but here's an example of what the manufacturer recommends.
Each Season disassemble, thoroughly inspect, clean, re-seal, and re-torque each wheel:
Replace wheel bolts each season
Wheel Bolt Torque:
1/4" bolts 15 ft/lbs. or 180 in./lbs
5/16" bolts 20 ft/lbs.
After thoroughly cleaning all mating surfaces with an appropriate cleaner, add a thin skim coat of silicone sealant to these surfaces, assemble wheel and torque bolts to recommended torque
Install a new valve stem
Add a thick coat of silicone sealant to the drop center area of the wheel and let it cure for 24 hours before initial use

There are a lot of commercial bolt houses around the Seattle/Tacoma area that I am certain exist in Cleveland too. They are listed in the phone book under Fasteners-industrial.
