Re: Undercoating, is it worth the money?
it all depends on WHAT type of coating you do, and WHEN you get it on
if its a used truck, you are too late to do any REAL good
you will just trap crap in between the metal and coating
the time to do it is when its NEW before it even gets wet!
the ral problem happens when there are nooks and cracks in corners and such that get missed, and then salt water from road salt finds its way in, water dry's and salt stays and eats away at metal
so the coating itself can TRAP water/salt behind it and still rust your metal away
it can help slow things down, BUt its not a sure saver in any way shape or form
rinse the under carriage well often in winter time and spring, and park it some place where its NOT over moisture all the time, like a cement pad or the likes
parking over gravel or dirt or grass, will cause more rust to form as that stuff hold nothing but moisture?
