I've been using 6006 off and on for about 2 years, and have been able to use all of my fragrances with this wax. I also have had problems with the holes, but I found that the wider my jar, the fewer problems I had. I mean, I had tons of holes in my jelly jars, but when I switched to the Salsas I had a lot less. The only thing I didn't really like, besides the holes, was color absorption. It seemed I had to use more dye with 6006 than I do with 4630. I also use zinc core wicks with this wax and haven't noticed any problems. I did wick down just a tad on some fo's and jars, but that was about it. Hugs, Jems
