All,
I've been using 3x foam polish over the years and I don't feel it actually does anything. Nothing that I can see except put on a show. So why not switch it to a detergent and get some (albeit very little) benefit?

Ryko actually uses a tri foam wax which can be used in either a touch-less or foambrite wash and goes on just before the wax in either wash. The tri foam detergent is for a brush wash only and is applied at the beginning of the wash process. The tri foam wax does bead water but is mostly for show and should be rinsed off and followed with a wax, sealer or Rain Shield.
