Since there can be an electrolytic reaction between the aluminum bottom bracket for the crank and the carbon fiber that surrounds it, I am applying a layer of fiberglass between the two. The fiberglass will insulate the aluminum from the carbon fiber. Since aluminum should be etched first before applying epoxy to it, I am using the West System's 860 Etching Kit to etch the aluminum in order that it better receive the layer of fiberglass.
The etching is a pretty quick process... about 10 minutes. The "wait" is the time it takes for the West System's 105 resin with 205 quick hardner to solidify before I can insert the bottom bracket in the fork.
