I've never noticed Lowe's being worse than other stores. When we go shopping in town, there's a Lowes, Menards, and Farm & Fleet within a mile of each other - Lowes and Menards on the same block. Menards is the cheapest, but the store's layout sucks, it is hard to find a sales assistant, and the quality of their products, especially lumber, is so bad I almost never go there. You never know what you're getting when buying hardware nowdays. Thanks, China. When possible, I put out the extra money for Grade 8, although it often doesn't have a pretty finish on it. GoreWound, I like using shrink wrap on any wiring job, too. Harbor Freight has it cheap. But Plasti-Dip works great if you don't mind the trouble of brushing it on (or dipping) and waiting for it to dry. Dries fast- and is the best seal you can get on a wire job. Also, you have to have enough room (and remember!) to put the shrink wrap on the wire BEFORE soldering! Not a problem with plasti-dip.
