Rain X anti mist stuff

[JMorgan]

Been using rain x for years, great stuff. Washer bottle additive for the last year or so, excellent. Just tried the anti fog stuff on the interior glass, brilliant stuff. Applied the day before Chatsworth so on the way home, damp clothes etc and not a bit of misting up (except the bits I missed around the edges. Still working after todays moist atmosphere.
No I don't work for them
