Yeah that's what I was thinking, you wouldn't want it to strip your wax off once you've applied it especially if you use an expensive wax!I have no idea tbh. It's the Autobrite Magifoam.
Are you just worried about it stripping protection/wax?
Autobrite claims it is LSP safe so it shouldn't strip the wax, I'm always skeptical about snowfoam though for this reason.
I bet you'll find the snowfoam dead convenient in the winter months... as long as it's not so cold the snowfoam freezes
