Best undercoating?

Just got a 2023 in Ontario , had the dealer apply undercoating after getting neighbours recommendation who had his done 8 years ago on a Tundra . They can touch it up if necessary at no cost . Company that distributes the product actually started in same town as the dealer . Kind of a cross between runny beeswax and fluid film . I can look up more specifics if anyone wants . In winter the truck needed to be in shop overnight to warm up and dry prior to application so got it done prior to pickup .

 

Just an update on my previous post . Ran into the neighbour that recommended the dealer undercoating to me and was asked if I got it . He said he has been under both his and his son's truck and seen the difference between rustproofing and not rustproofing . Both are similar ages . He is now certain good rustproofing is money well spent .
