auto finesse wax mate...heard some people say the adam's americana wax applicator is also good (hex style handle)
most foam applicators can get a decent life span. I generally toss them in a bucket of APC and water after a detail. they clean out very well.
[h=2]Adam's Yellow Hex-Grip Car Wax Applicator --[/h] Why is it advised not to store this in a sealed plastic bad?
The reason might be that if the pad is not completely dry following use, mold could grow. I've read that it's okay to store them in bags, but leave the bag slightly open.
