    Do yourself a favor and buy a good spray bottle and fill it (AND MARK IT!!) with this stuff. You will use less, cover more evenly and find yourself using it all the time. Blasting or not blasting you will find uses for it!- this is the best item Eastwood sells.

    I use this stuff any time I'm painting steel, regardless of what paint I choose.
    GP is right, I believe a water rinse is in order. One time I didn't and it affected the paint. Every other time I water rinse and the adhesion is great!
    works good, if you can get it. (Posted on 6/12/13)

    Its difficult to evaluate a product that is not well understood. Phosphoric acid is normally neutralized following application by rinsing with water and then air drying.

    The directions say to spray on, let sit for a spell and then wipe off. Repeat until metal is clean.

    The problem is that these directions are of little use as the procedure does not provide visible results that give one confidence all is working properly. Multiple sprays and wipes lead to streaking. One application and wipe leave a nice gray finish. Another application leaves a white streaking residue.

    The lack of neutralization with water makes one wonder if acid residue is being left behind that will affect the primer and paint that is to follow.

    A better, more detailed, description is in order. Unfortunately, Eastwood does not have the tech support it advertises. You can't get anyone on the phone, the do not call back when you leave a message. I'm beginning to believe Eastwood has lost their way.

    I used the Eastwood Gel Rust Dissolver to remove all the rust from my dashboard because it could get to areas sanding wouldn't. After rinsing, the metal flash rusted quickly, so I hit it with the After Blast, and the flash disappeared and left a nice coating of zinc behind. It's a combination that worked excellent.

    This is my first time using the product and have been applying to an antique tractor. We had problems with flash rusting after paint removal and using wire wheel, so we tried this. It has worked great in the high humidity and we have not had any reoccurance of flash rust.

    The first step to a good paint job is prep work and this stuff is a must. Cleans and etches bare steel for paint and really gets it to adhere well. May sound pricey but I only used about a quarter of the gallon on an entire frame and that was using generously.
    Great stuff! (Posted on 4/21/11)

    This stuff is excellent for use on any bare metal! After media blasting some rusty areas on the sheet metal on my '67 mustang I found some heavy pitting in areas. I used used paint stripper on the non-rusty areas and used after blast on the blasted areas. Once it had dried and phosphetised the metal it matched the original surrounding phosphitizing metal from the factory of 44 years ago. I filled the pits with metalic filler and coated with 2K Urethane primer and I feel very confident these steps will prevent any future rust.

    This is great stuff to have in your garage to treat any bare metal. I cleaned some other small parts and once the surface was phosphitized I hit them with a coat of Zero Rust and they look like new!

    Product does exactly what you need after blasting. I use it after grinding also and works well. Turns you metal grayish color when it finishes drying and is ready to coat.

    Yes has a strong odor, follow directions. I have many small items to blast, this is a great way to get them all ready and keep them in good condition prior to painting. It goes a long way. Highly recommended!
