Input on undercoating please

[Slim]

I want to buy some of this stuff ..... http://www.canadiantire.ca/AST/brow...~0477904P/Rubberized+Asphalt+Undercoating.jsp ..... and spray the whole underside of the truck. I'd also do the i-beams and radius arms and rear end.

And then along the rockers (along bottom edge of truck) and then my bumpers (because I want them black anyway).

Yeah?

I don't wanna see any rust on my stuff. Ever. Period.

I shoot my underside with 3M undercoating about twice a year and I love the stuff. Don't know about the bumpers.....

Why twice a year???

Isn't this stuff supposed to be more like an "apply once and fo'geta'bout'it" deals?!?!?!

Is there more I (we) should know?

ya twice a year is jsut way way way over kill. jsut amke sure all the dirt and stuff is off. my dads buddy uses POR and thats a professional spray on more like rhino lining or line-x. other wise jsut get a high quality RUBBERIZED undercoating

Okay I guess I didn't word that really well. I give the areas that need it a blast before winter, and touch it up a bit in certain spots in summer. I guess I made it sound like a lot more than what I actually use. The 3M pro grade rubberized stuff is the best spray on stuff I've ever used.

i used the marhyde on my carp shootin deck and its been on there almsot 2 yrs and shes startin to fade now but is still on there good. i only used it cuz it was like $4 a can

 

[strvger]

i use the Marhyde on the under body where no one will see it. i use the 3M along the lower body, rockers, etc. as it looks much nicer and still does an excellent job. the Marhyde is cheaper here than the 3M and that is why i use both. both work well, one looks better when finished. what we really need is some Rhinoliner or Herculiner in a spray can!

 

[snoman6115]

one thing i did notice about the marhyde is that if i let it dry in the sun, it would turn brown and crack sooner than if i let it dry in the shade

I have used the Plasti-Kote and Duplicolor bedliner in a spray can, it works pretty good. I have it on the grille guard and rollbar in my Ranger.

Thanks for the input so far everyone. I've been doing more research and digging deeper into this. Very interesting stories to be read out there.

I've also been thinking that it would be a good idea to do inside the doors and tailgate, too!

You know, i'm almost tempted to say i'd do the whole truck on the outside, like the flat black theme, if there was something that would "finish up" nice enough. Am I crazy or does that sound reasonably sensible?

FAKE ANSWER: That would be awesome! Undercoat your whole truck instead of paint! And finish it with a layer of clearcoat!

REAL ANSWER: Yes, you're crazy.

When I find a better box, I am going to flip it upside down and lay it on thick to curb rust.

After I repaint the truck (that is really reaching out into the future)I would also like to do from the lower bodyline down for stone chips as well.

lol

Okay, so i'm not really seeing a specific "no" answer there .....

Hey I'm the dude considering undercoating my tonneau cover, so who am I to say no?

I'd stay away from the stuff that hardens (dripless). Look at the sprays that stay fluid, like Krown. It'll get into all the tight spaces and will displace moisture. The rubberized stuff can trap moisture between itself and the metal.

I'm a big fan of Krown. Have done all the cars I've ever owned. Not only does it fight rust, it makes wrenching on things underneath a lot easier. No more crusty parts or rusty seized bolts. I'm bringing my brand new '09 to Krown in a couple of weeks.

You can DIY Krown by buying spray cans. I think Husky carries them, but for sure Krown does. It's called T-40. When Krown does it for you, they not only spray the surface they drill hoes and get the stuff into the door, rockers, etc.

Whatever you do, use the oily stuff that drips.
