  • Rust Encapsulator Gray 15 ounce Aerosol
Rust Encapsulator Gray 15 ounce Aerosol is rated 3.8 out of 5 by 17.
Rated 4 out of 5 by from Glad such a product exists! The sidellight windows on the front door of my office turned out to be steel covering foam core. Over 12 years, salt water rusted & bubbled the bottoms, especially where the moisture was held in the contact points with side wood & ground. Used a drill bit and metal brush to remove most of the rust. Sprayed 2 coates of the encapsulator and painted over all. Still got some bleed through so repeated the process with 2 more coats. This seemed to hold. Having brass kickplates installed on the exterior bottoms and siliconed around the edges to prevent or retard further damage. The encapsulator seemed very good..

Rated 4 out of 5 by from SFSG Can you figure out what sfsg refers to? ;-) I've only recently used this product so I cant comment on how well it works. I will TRY to remember to come back here after a year to comment on how well the product is performing. The product was easily applied, remember to shake the can often it makes a big difference. I did have a little trouble spraying my roof vents which required the can to be pointed downward and without shaking regularly it quit spraying paint and only sprayed air but shaking the can regularly solved that. Delivery was supersonic, I think I got it the day after I ordered. For now I'll give a 4 star rating because I dont know how well it works yet, I'll be back in Feb 2016 to update (yea thats gonna happen) ;-)

Can I use PQR15 Cleaner/Degreaser first before applying Rust Encapsulator? Are these products compatible. If yes, after applying Degreaser, do I then apply Encapsulator directly or some additional prep needed?  Does Encapsulator come in any blue colors?

Asked by: stevecamino
While the Por 15 degreaser would work our Pre is a better bet to ensure a clean surface for the Encapsulator to adhere to. The Encapsulator will not come in a Blue color.

I have a 57 Chevy with the original factory rust proofing sprayed in the wheel tubs and bottom of the car. Needless to say this is extremely hard to remove and is unsightly, can this be used to cover the old rust proofing or is there a better option?

Asked by: Tom Son
I took a propane torch and heated to remove this on my 56. I've heard restore guys do this also. Even with a media blaster it won't come off otherwise. But I would not spray anything over it as it would have to be extremely clean in order to bond with any other material.

I have a Eastwood SCT and I am planing to remove as much rust with it as possible then encapsulate in case I did not remove everything then paint on top of it.  Is this good idea or should I use the SCT then use primer instead of encapsulating?

Asked by: Kedeiv
It would always be strongly recommended to remove as much rust as possible before applying the Encapsulator. The SCT would certainly be an excellent too,l to use for this instance.

I have a satellite dish. It has surface rust. Can it be used on this item? Also, at what temperature can it be applied and how long does it take to cure?

Asked by: J Scott
You can use it on any rusted surface with no issues. It should be applied as close to 70 degrees as possible. It will take only a few hours to fully dry at 70 degrees.

I want to spray for rust in the front door posts of a 1964 GMC after I peel the roof. Will the 360 degree extension fit other cans of rust preventers?

Asked by: Bud C
You would want to use the internal frame coating not the encpasulator. The encapsulator requires prep.

Rust Encapsulator Gray 15 ounce Aerosol

Item #14822Z Brand: Eastwood

Reformulated with TWICE the corrosion resistance!

In stock

Only $19.99

Sale $14.97


Stop rust in its tracks! Our Rust Encapsulator (Gray) has been reformulated with TWICE the corrosion resistance!

  • Gray in color
  • Twice the corrosion resistance of our original formula for greater durability (tested to 500 hours in a salt-spray chamber)
  • Epoxy-fortified for better adhesion and topcoat compatibility
  • Penetrates deeper to prevent rust from spreading or forming, even in hard-to-reach areas
  • Cures faster, and the low-VOC formula is acceptable in California
  • 15-oz. aerosol covers about 10 sq. ft.
  • As seen on "My Classic Car" TV show

You thought it was good before...wait ’til you try this Rust Encapsulator! It seals and stops rust and corrosion from spreading, but it performs even better than our original formula. Tested against well-known brands, the Eastwood Rust Encapsulator has proven to be superior in sunlight resistance, preventing rust creep, and overall durability.

Unlike off the shelf under coatings, Rubberized Rust Encapsulator can be applied directly over rust and without the bubbling that creates air pockets thus trapping rust. Since its engineered with high tech flex agents, its pliable finish protects surfaces from abrasions, road hazards and deadens sound. So durable it exceeded 1,000 hours of salt spray chamber testing, this surpasses the standards for a 2 component catalyzed coating! Simply apply directly over rust or bare metal; no need to topcoat. Remains flexible and durable. Satin gray finish.
