Does 4wdetail rust prevention really work? NOT SPONSORED, or is it money down the drain?

This week we test 4wdetail rust prevention. After keeping the rust off this car for over 30 years,  we can't drop our guard,  so before and after every beach trip we spent hours in rust prevention, so we really want to test if 4wdetail really works or should we just keep doing it the way we have in the past https://linktr.ee/goingoverland #goingoverland https://www.solar4rvs.com.au/ https://horizontouringproducts.com.au/ https://auxbeam.com/ www.viofo.com https://bit.ly/3sPLNwE #campinggear #4wd247 #4wdaustralia #4x4australia #campertrailer #campinglife #offroadcamping #offroadtrailer #camperlife #campingaustralia #overlandtrailer #overlandtravel #goingoverland #travelaustralia #caravanningaustralia
