Undercoating in a can

People have gotten some incredible NVH reductions using this stuff on uncoated bottoms of economy cars. Never used it myself though.
I looked on the Petroleum Service Company website and read on that product. As a UPS semi mechanic, I know of that type of coating. I have no experience of that particular brand however. If it's anything like I see at work, buy and use with confidence.
The brown trucks are rubberized undercoated? Did they do any studies?

I've undercoated my cars before with fluid film type of rustproofing. I've applied up to five gallons on cars. A couple cans just wouldn't do it for me.

My thoughts are, little (or less), but more often (like once a year), might be be more effective.
I'm doing a test this winter with Fluid Film and two other products, applied to bare metal 'dog tags' suspended under my truck.
I'll post results in about a month.

I patch rocker panels on $500 cars with "Aluma-trim coil", rivets, self tapping screws, and bondo. Rubberized undercoating in a can is the natural top coat.
It seems to flake off at times. I've also welded frames and had the weld, more prone to rust, pop up through the coating.
But it has its place on beaters. I'd do a few coats of careful prep. Can't speak for new cars-- I'd go with a fluid film stuff, personally.

I've used it on the floor pans and structural portions of my new and newer cars. I touch it up annually. seems to hold off rust well. as you can see, my fleet is mostly older - and I have NO rust problems.

Also subscribed. My 300M is getting pretty cancerous underneath; once spring comes around I'll deal with it. No idea what product to use though.

I have a gallon and cut it with kerosene, sprayed it on the mustang. The wife is very upset with me because it smells like a sheep's rear end.
Hopefully sitting over the winter, it will dissipate.

haha, my wife HATES the smell too. She always knows when I touched up the FF!
Digging this up in case there is an update to how this protects.
Just curious but what about using AMSOIL's Heavy Duty Metal Protector?

Same kind of stuff just waxy instead of a "curing" rubber. Marginally more self healing, but can still allow moisture underneath. I'd still topcoat it with an oil or fluid film type product.

Use waxoyl. It brushes on, it self heals and it stays put.
I need shares in them for the amount of it I buy!

Waxoyl is fussy, does not like thick coats and i've had it harbour rust underneath on many occasions
