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) ;-)

Rated 5 out of 5 by from Great product This stuff works, I wire wheeled the roof interior, inner frame, and under the dash where it rusts and is hard to get to. Very impressed with the penetration into the surface. Good to great coverage.

Rated 5 out of 5 by from Good coverage - love this product This is my second or third time using this product for a car truck. Great coverage with a nice, clean look when dry. Appreciate that it will stop rust in it's tracks. Thanks

Rated 1 out of 5 by from Completely useless and a ripoff This product does not work at all and is nothing more than regular gray primer making false claims (and I followed the instructions to a T). After using this product, I would be very reluctant to purchase other products from Eastwood. If you want to protect your car from rust, do NOT use this product.

Rated 1 out of 5 by from Waste of money and time Does not perform as advertised and rust comes back fairly quickly. Any conventional paint should work just as well.

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.

Can I use this as my primer for my whole truck? I believe i already got all the rust off, but am using this just in case. I have sanded the truck already with 80 grit and it is down to the factory basecoat with some spots sanded to primer and bare metal.

Asked by: Cody99999
Technically yes, but no. If you are that far along I would recommend using an epoxy over the entire vehicle.

Is the color of this gray when applied? Does it retain the gray color after drying? I have six rusted vents on roof, my shingles are gray so if this is also gray it would save me from buying gray spray paint also.

Asked by: Not very handy
It does dry to a gray finish, so it should be close to the color you need.

Rust Encapsulator Gray 15 ounce Aerosol

Item #14822Z Brand: Eastwood

Reformulated with TWICE the corrosion resistance!


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

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.

  • Gray
  • 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
