Hi guys,

I am contemplating for an undercoat since raniy days are fast approaching. Upon searching about good shops that does this service, I stumbled upon a forum that made me think twice.

"I used to work alongside the inventor of the 3M undercoating system and guess what he said..... "Don't use it." Straight from the horse's mouth na yan. Been there, done that, no more undercoating for me. Regular chassis washing/cleaning/detailing is all you need. Rubberized undercoatings will just hide the rust until it's too late to do anything about it. Body repair ang bagsak mo diyan.

Don't listen to media and marketing hype. You don't need to buy lots of fancy stuff to make your car look & run well. Remember, 40 years ago they didn't use undercoatings in Wolfsburg and look at all the VW's that have survived since then. Now look at the recent restorations with undercoatings and crusty floors. Find a pattern? Keep it simple. HTH!"

"The rubberized coating only hid the rust. When the coating hardens, it becomes brittle and when a stone or some object runned over by the tires would hit it, a crack develops and its where water would seep through. The water stays in between the metal and the undercoating, never having the chance to dry up. You would see it more in the wheel well area. "

Since the missing link here is when the undercoat hardens and get cracks, there will be room for water to store which will create rust through time. Now I was thinking if the bedliners being applied into pick-ups are strong enough to be applied undercoat? Or am I being on the wrong path?

Thanks for all your comments!
