Just got the rocker and floor repair panels for my truck,gonna wait for the snow to melt then wled them in, should i lizard skin with the sound control and ceramic insulation or should i just por 15 it???

 

Last year it sanded my roof down to bare metal por 15ed it with a brush and i have rust coming through the zircomiun primer all over my roof

 

When using POR-15, instructions say paint
over it with some other paint if light hits it.
I painted over it on frame with rustOleum.
Holding up good.

 

I would use Rust Bullet. That stuff is awesome. I've had no luck with Por15, even after proper prepping.

I also used lizard as a sound deadener for the inside of my crew and not sure if it helped.

 

There is also a paint by Magnet sold at Napa called Rust Preventer I think. That stuff cures HARD. It's best to paint it in more humid conditions since it uses moisture in the air as a catalyst to make it "kick". I've heard not to use it in a workshop heated by a woodstove to make it cure for that reason.

Put it on my uncles frame. It is some HARD stuff.

 

dzl_damon,
I think you're thinking of Chassis Saver by Magnet.
I've used it and love it.

i used chassis saver. it does not hold up to sunlight or uv rays.... meaning if you take your bed off to paint the chassis put it back on right away after the paint dries
