    DI2 heatshrink alternatives?

    disassembled a dura ace di2 bike today and really had a great time with the heatshrink for the internal connector/wires. frame is a trek madone 6.9 i beleive. the stock shimano shrink tube has glue on the inside to keep the connection waterproof. its a bear to remove while trying not to cut or nick the wires. any alternatives to heatshrink with the glue liner? the heatshrink also keeps the connectors from pulling apart. i was thinking dielectric grease and regular shrink tube, not sure. just trying to make it easier for the next guy or gal the comes along.

    reptilezs: Try self-fusing butyl or silicone tape. It was originally developed for the electric power and aircraft wiring trades. It only sticks to itself and can be easily removed with a razor blade. You stretch it while applying and it makes such a tight seal you can probably do without the dielectric grease. It works great for finishing off handlebar wraps as well. It doesn't creep like electrical tape.

    If you need to replace any connectors I'd highly recommend you consider Anderson PowerPoles. They are available in a number of sizes (amperage ratings) and colors for color coding if you need. They snap together pretty solidly but there are also locking means available for the mated connectors.

    I'd go along with this.
