Eastwood rust encapsulator platinum

[autumn ash]

Anybody ever use this stuff?
Id like to use this to do the underbody of my car, frame rails, wheels wells, etc.
Is anybody not using undercoating and instead just using a strong paint like this?

i have tried the encapsulator on small jobs, it covers and is suppose to seal the rust. After using i sanded and the rust is still there.This was a test and i have no long term results. After that i used fast etch for very rusted deep pits. Left the fast etch for a few hours and the rust was completely gone and the pits were shiny grey right down to the bottom.

POR 15 I have heard works well...

Loosen your drain plug by half a turn and drive the piss out of it. Once your oil light comes on, refill the engine with oil and drive it again. After a few cycles of this, the bottom of your car will have the best performing undercoat in town. You're guaranteed not to rust or chip after that.

The problem with Por-15 and the Rust encapsulator is that they are both photochemically reactive. Supposedly they will literally crack and flake off unless you paint over the surface afterwards to prevent sunlight from ever hitting it. The back of the can states that and I’ve seen photos online of people showing the coating coming off.
Perhaps someone here who’s used it can comment on that issue

I like Por-15. It is very hard stuff, goes on easy, seals well. I can't imagine anyone unhappy with it. Flaking off? I would suspect poor prep, you must remove loose stuff not just paint over. Instructions recommend at least two coats.

Por-15 / Dom - 15 is what most of the trailer manufactures spray on their trailer frames. Anyone had one last 6 months before it rusts....

i used to oil my truck chassis with used engine oil.If you do that avoid any rubber components...they will swell and deteriorate with repeated use. Spring and fall application works fine but the used engine oil doesn't last.
I buy Krown or Rust check now and it still requires periodic application

From what I've seen personally, the outer color flakes off but the white encapsulator part seems to stay intact. I personally wouldn't use it for anything other than brushing inside of crevices that you can't remove rust from to just help buy some time.

No,it wasn’t poor prep work. Supposedly the stuff if sensitive to sunlight and has to have a top coating. Someone on another Mopar site showed photos of it cracking and coming off after a few years and they had a discussion about it.

From Por-15’s website FAQ page-

“MUST I PAINT OVER POR-15 TO MAKE IT LAST? No, but POR-15 has an ultra-violet sensitivity and must be topcoated if continually exposed to sunlight. Once topcoated, POR-15 will remain effective for many years.”

FAQs

So they are saying basically that the answer is YES. It does needed to be topcoated if you want it to last for any period of time. It would be fine to use in a trunk or areas where sunlight won’t hit it. But anyplace outside the car where it’s going to get hit by sunlight should be coated.
But like I said I’ve seen photos posted by people on the finned mopar website showing it flaking off with time and rusting underneath because it wasn’t topcoated.

As far as the Eastwood Encapsulator,I’ve read it has a higher uv resistance but am not sure how much better it lasts than POR-15

Sounds to me like they are saying thier product is meant for the underside of a vehicle, and if used on the top side (not the intended use) it needs extra care
