Eastwood After Blast Metal Prep is rated 4.5 out of 5 by 35.
Rated 5 out of 5 by from This Stuff WORKS! I bought a gallon of After Blast as an alternative to using Acetone. It not only works well, but it gives a nice protective coating to the parts I'm going to powder coat. I use it in conjunction with Eastwoods Pre aerosol spray. I place my part in the blast cabinet. After blasting, I wipe it down with Pre. It goes into the oven for out gassing. After it's done and cools down, I finish it off with After Blast. The results are FANTASTIC! This product works so well, I just ordered another gallon to have on hand as a back up. Get it. I dont think you'll be disappointed. It's worth the money if you're looking for nice results!

Rated 5 out of 5 by from Good Stuff! I've been getting more and more into powder coating and was looking for something economical for cleaning and treating and this fit the bill. I've prepped and coated at least a dozen parts now with it and it works well *as long as you wipe it off*. Your part must be a nice even grey color with no dried residue otherwise the powder will have defects or not cover the area at all. Be very careful in tight, hard to reach areas.

Rated 5 out of 5 by from Works as advertised Had my car plastic bead blasted 3 weeks ago. Brought it home and wiped it down a couple of times and still no flash rusting. Pretty amazing since it has been raining and or 80% humidity since I brought it home.

I had rally wheels soda blasted, they are steel wheels with chrome centers. Do I have to keep the Eastwood after blast metal prep off the chrome centers for fear it will etch the chrome, damaging it?

Asked by: Bill
We have never tested any of our products with a Chrome plating process for compatibility. We would have to advise you to keep this product off of the chrome plated areas.

How long will this protect the bare metal from rusting before priming?  

Asked by: Brettsvn
There is no way to gauge this- unfortunately too many variables would play in. As log as it is stored in a controlled environment and not subjected to the elements - it should last several months for you at the least.

After wiping down the sand blasting and wiping it down with 11971ZP how long can you leave it in this state before priming is needed? What is a good primer to use when you don't know what paint you will be going with yet?

Asked by: Sam I am
Once the After Blast has fully cured, all you will need to do is scuff up the panel, wipe it with a wax and grease remover. Epoxy Primer would be the best primer as it will accept a more of a verity of finishes.

I had my car fully sandblasted and garaged. Within a couple of days we got some rain and moisture creating some flash rust. Will this product remove and reduce future flash rust?

Asked by: gizmoe
This is meant more as a preventative. You would be better of using the Fast Etch for your current situation: https://www.eastwood.com/rust-remover-eastwood-fast-etch.html

If you use Afterblast on panels that have been spot welded together you obviously can't wipe the Afterblast off in the crevices. Is it still O.K. to use as long as you allow the Afterblast to dry fully?

Asked by: John
This will be fine as long as you allow it to fully dry.

I plan on using this after SODA blasting. I've read alot of people having paint adhesion issues after using soda, but I feel it's best for my application, will this take the left over film from the soda off the surface? wil I need to do something extra?

Asked by: Josh
After Blast would be great to apply after the Soda Blasting. When your ready to paint, wipe your metal down with some Acetone.

About Eastwood After Blast Metal Prep

After Blast is designed to clean, degrease and etch freshly blasted or sanded metal prior to painting or powder coating. Use with a plastic spray bottle to liberally apply to the part, wipe and reapply until all contaminants are removed. The blend of aqueous cleaners and phosphoric acid properly cleans, etches the metal and leaves a zinc phosphate coating that is excellent for paint, primer or powder adhesion. Also protects the metal from flash corrosion for extended periods. Use on all your fresh cast iron, steel or aluminum components.
