EW After Blast is rated 4.5 out of 5 by 28.
Rated 5 out of 5 by from Remove and prevent flash rusting! I bought After Blast as it was advertised to clean and stop flash rusting after media blasting, grinding and stripping. I was stripping my 73 Challenger and was having problems with flash rust, especially in the high humidity Houston area. To my surprise, this product cleaned the metal extremely well. Alll the rust, even in small scratches, was removed. I've been using a cleaning disk to remove paint and Bondo, and the swirls in the metal left by the disks seem to be removed by After Blast. The metal actually LOOKS really clean, too! I was a little concerned that one jug of After Blast wasn't going to be enough for my entire car, but I was pleasantly surprised at how far just a little went. I can now use that extra bottle I bought to clean small parts before refinishing as well! Overall, exceeded my expectations and I actually glad I bought this product, and I think you will be too!

Rated 5 out of 5 by from Great stuff! 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!

Rated 3 out of 5 by from After blast I bought the product for prepping the steel for powder coating. I manufacture a motorcycle rack to transport you dirt bike, sport bike and Harley. I built my on oven. I also bought a dual voltage gun from you, very unhappy with the gun, working with Sean to replace it. When I received the product it leaked in the plastic bag and I could not read the instructions so I called and the customer service person had to read the instruction I guess because he put me on hold. I still not sure do you spray and wipe it off or let it try.? I'm pretty sure you don't use any water. Any clarification would help Thanks Richard

Rated 3 out of 5 by from Expensive but works well. I've been blasting parts for my restoration, but am not ready to prime/paint/powder coat them till I have a batch ready. I tried Metal Wash afterwards and it worked but not perfectly. I would still get some flash rust in spots. This works a lot better for protecting the metal afterward though it's slow. The fumes are very potent, even in an open garage they're strong. Use outside or with a mask. A little goes a long way, I have a spray bottle with it in and just a light application is sufficient, and I usually only need one. The parts I've done have been sitting in high humidity heat for a week or two with no signs of flash rust. Still, it's not cheap for something they want you to apply liberally, but it does seem to work. I have yet to see how it affects top coats as I'm not ready to paint or powder any of the parts yet.

Rated 5 out of 5 by from After Blast Hi, I have had more of a chance to use After Blast and I must say it works really good for powder coating. I'm about ready to buy my second gallon but to my surprise you have raised the price, I already thought its was to expensive by the time I get it with freight its well over $50.00 that's a little to expensive. Is there a way to thin it out.? If not I may have to look for a another solution. Thank You Richard

Rated 4 out of 5 by from Eliminated flash rusting 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.

Rated 5 out of 5 by from Great Product! "But Please Read" I have a 71 Camaro that I am restoring sandblasted the car, there are some spots that had the factory e-coat (Factory Primer) still on the car. this was due to it was in great shape. When I used the After Blast on the bare metal it worked Awesome!!! it cleaned and etched the bare metal perfectly! But when the after blast got on the primer it leaves a residue Just be sure to clean it off and scuff the primer. I cleaned it off with prep all (a wax and grease remover) then wiped down the entire surface including the bare metal again with the prep all again using the blue shop towles wiping each wipe with a clean side of the shop towel. I used ppg epoxy primer and followeed it with Eastwoods chassie black paint. I am very happy with the results and happy with the Eastwood products!!!

Rated 5 out of 5 by from Excellent Product 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.

Is After Blast weldable?

Asked by: ruckUS13
You would want to clean the area off with a wax and grease remover before welding where the After Blast has been placed.

Is this rated for MILC10578

Asked by: Charlie1212
Our Afterblast is not designed to meet MILC10578 but does appear to already fall into it partially since it is a phosphoric acid solution that will etch metal and provide an excellent surface for paint adhesion. Except ours is already suspended in a solution and does not need to be diluted.

I have tinned some areas for body solder and was unable to apply the solder at that time, treated the area with after blast do I need to clean the area before soldering Thanks

Asked by: 1958 jag
You will need to re tin the area to make for good adhesion.

Blasted my 68 Mustang, cleaned surface with acetone and applied After-Blast, Some areas have turned white or light blue. What happened and what do I need to do to get ready apply the Epoxy primer? Tks Aubrey

Asked by: just and old guy
All you will need to do is to wipe the surface down with fresh After blast prior to moving on to primer. Just make sure to wipe it dry as well as to not leave too much on the surface.

I have a panel that is partially metal but am leaving some areas of paint untouched. If I use after blast and it comes in contact with paint, is it ok as long as I primer over the areas of paint that get etched? Same question for body filler?

Asked by: JFHR
This product is designed for bare metal. We would not recommend heavily wiping this on a painted or body work area.

I need to find out if your after blast is compatible with Omni AU MP170 Epoxy Primer by PPG Industries.

Asked by: Rob79
We have not be able to test the After Blast with other primers, however it is simply a cleaner and should not have any reaction issues.
