I bought a couple of the fancy 4" x 6" SFX Pro wax applicators from Autopia about a year ago (http://www.autopia-carcare.com/son-sfxpro.html), but they really didn't work too well for me for applying sealants. So I started using them a few months ago as tire swipes, and they are the best swipes I have tried - by far! I've probably done 50-75 SETS of tires with each and they aren't even showing any wear...they hold up forever. And they have the perfect texture IMO for applying tire dressing. I've washed them a couple times to clean them up, but that's it. Previously I was using tire swipes that cost $4 each and would only do about 20 sets of tires before I had to junk them...at $5 each, these babies are a bargain!
