Regarding the WD-40 Specialist, I was just about to put some in my Amazon cart last night while I was shopping for some cleaning brushes, until I decided to read some of the reviews. Several of them cited that it eventually turns tacky. Not sure how long it took for that to happen, but I was curious if the same has happened to the sample pieces in this test?
ETA: I ended up going with two different kinds of the Hornady One Shot. I really wanted to try the Frog Lube, but it just seemed too expensive to me.
