Best Undercoating?

[KB93z28]

Gonna start undercoating a few pieces under my truck a little bit, Im wondering what you people think is the best undercoating?

[Grovlet]

I Like POR15

My buddies have used it on their trucks with good success.

POR is only good on stuff that is heavily rusted/scaled. otherwise it's useless. if it doesn't have a rusty surface to stick to it will just peel off in sheets.

for something durable, i like using herculiner bed liner. much better and more durable than the spray on rubberized undercoating crap.

POR doesn't peel if you do it right. We've done roll bars and brand new rears no problem..

i would just use regular 3M undercoating for your truck

you need to prep the surface with etching compound first. then POR will work Awesome! other wise if you really dont want to hassle with it get some spray on carp and just keep up on it.

Well I wanna do my k frame on my truck, its got some surface rust on it, I plan on cleaning it up with a wire cup real nice, and then spraying it with something think that would be good enough prep for por15?

yeah, just buy the super starter kit off the por-15 website, it comes with metal ready(etching compound).after you clean it up with the wire cup just hit it with the metal ready and you'll be good to go

if rust is the problem, use rust bullet or master series. both work better than por15 with less hassle and no added prep steps or products to double the price and work involved.

...and if you don't do it just right, it you can peel it off with your fingernails. even if you DO do it right, if you chip it the same thing happens, especially on new metal. POR was the shit like 10 years ago, and its nice because you can find it in hardware stores and stuff now, but i'm telling you there's way better stuff out there now and for less money.
