- Eastwood After Blast - Metal Prep
how do you apply this product and is it ok to drip on driveway and just wash off with hose ?
Do you need too, or should you, rinse with water before painting or powder coating?
Will this coating dissolve if exposed to hot lubricating oil such as inside a transmission? If so, I'm concerned that the zinc and phosphate would change the chemical properties of the oil.
How long will this product protect against flash rust? Specifically, I am looking to protect my blasted frame (stored in a garage) for several months until I can paint it in the spring.
Is this recommended for cast iron that has been sandblasted?
What's the difference between this and fast etch?
After blasting to bare metal and then applying After Blast, does the zinc phosphate layer need to be removed before priming or can I apply epoxy primer directly over After Blast? Will Eastwood PRE-painting Prep remove the After Blast zinc phosphate layer?
is the zinc phosphate that's left behind black In color or grey? and how is it best removed before painting?

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.
Use after abrasive, soda blasting or sanding/grinding operations to assure of a clean paint ready metal surface.
Use in well ventilated area and wear rubber gloves

Use on cast iron steel and aluminum to clean and properly etch the metal for coatings. The phosphoric acid will etch the metal and provide an excellent surface etch for paint adhesion. Use on frames, sheet metal engine blocks and suspension components after blasting. Do not apply to painted surfaces, chrome, plastic or glass.
