I needed a new roll of high quality electrical tape. It allowed to me make my account have 252 reward points. Just enough to redeem for next time. [ Andrew  Jul 28, 2018 ]
A
there are plenty of crap brands, this is not those. never seem to have enough electrical tape when i need it. ends up being used for much more than electrical purposes. wrapping it around door internals quiets some of the clatter associated with cheaper cars; makes opening and closing have a more premium feel. if putting decent power to your door speakers you'll want to do some basic deadening at a minimum, otherwise you'll have rattles for sure. [ Jason  May 16, 2018 ]
