Eastwood Fast Etch 1 Gallon is rated 4.3 out of 5 by 71.
Rated 5 out of 5 by from Great Product I purchased the 32oz bottle to etch my 68 Camaro prior to priming. Once I had stripped the car down to metal I used soap and water to removal all oils and contaminants. I wasn't worried about bear metal rusting because I applied fast etch right after. This product worked great!! It didn't take long for it to start working. I did the whole car at once to I had to work fast before the product dried when removing the excess. I used to run a trailer mfg company and we used to acid etch our trailers prior to painting and it has the same finish. I also had a very rusty floor pan and it did wonders with it. You can't even tell it was rusty. I will purchase again.

Rated 2 out of 5 by from Seems to work but bottle top leaks Seems to work. I spray it onto patches of pitted surface rust and it does seem to neutralize the rust as acid normally would. I don't know how it will do long-term under paint but I have faith that it will hold. Bottle top leaks like crazy every time I use it. A simple washer would solve this. Hasn't E seen enough complaints about this to do something about it? I wrote to cs but of course heard nothing back. I'm going to pour it into a container and brush it on from now on. So the bottom line is that it works but beware the leaky bottle, especially since this is acid based. Would have given it four stars otherwise.

Rated 5 out of 5 by from Eastwood Fast Etch with pump 32 oz This stuff is great! It really does take care of the rust quickly and leaves a seemingly rust-proof finish behind. My only concern is that it seems to stay around and, if I get it into seams or tight areas, It might not be so good. I really don't have anything to base that on though other than my instinct telling me "it's acid... bad for metal" but, whatever, the zinc coating is supposed to compensate, I guess. I followed it up with some acetone per the directions and my subsequent coats of seam-sealer and paint seemed to adhere well. I will say it is particularly nasty stuff. I had to wear my respirator and gloves. It seems to clean up easily with water so no worries there. It makes a fantastic decongestant, exfoliate, and has a zesty, lemony flavor. Highly recommended on all counts.

How long will fast etch last once applied? I assume it can be reapplied?

Asked by: AZbaer
As long as the part is kept indoors it will last a very long time.

I used the fast etch and I have heave white build up even after wiping it off.  I have reapplied and scrubbed it with a brush and an still getting white streaks.  I have used thinner to wipe down as well as wax and grease no joy. No what?

Asked by: LDO 2011
The white residue is excess zinc phosphate being left on the surface. If you apply fresh Fast etch to wet the whole surface you can reflow this and then quickly dry the surface with a clean rag to remove the majority of this.

What drying time before priming

Asked by: Boss hodges2
This product is not a paint you let dry before moving on. You want to wipe off this product before it dries. Then from here you will want to re wipe the panel with our Pre Painting Prep prior to primer.

I recently tried out fast etch on some heavily rusted areas and the rust has turned black with small white deposits, is this similar to how the EW Rust Converter works or do I need to use multiple applications?

Asked by: Chris P
This is perfectly how the product is supposed to function. The white deposits are caused by excess zinc phosphate. All it would take is for you to re wet the surface with fresh fast etch to reflow the deposits and then wipe off all the excess. Now you are ready for filler or primer.

I used fast tech inside the windshield pillar of my Corvair to neutralize some surface rust on the inner layer and I will be making patches to repair the outer layer. Should I coat the treated inner layer with encapsulator? Or is fast etch enough?

Asked by: Dale780
You could spray our Internal Frame coating inside after some Pre painting prep for the best protection.

I wiped this Fast Etch onto a sheet of cold rolled steel with a rag to get off some mild flash rust. However, it caused white streaking all over the metal and know I can't get these streaks off. What is it and how do I prevent that or remove it?

Asked by: trey1
This is just extra phosphate left behind. Simply re wet the area with Fast etch to soften up and then quickly wipe the area dry.

I'm a little confused. I sanded my trunk lid down with 80 grit. Apply fast etch over it to help kill and remove the rust / pits. I wipe down with PRE prep and epoxy primed. Is that right or did I need to sand the zinc phosphate coating off.

Asked by: darthead
Yes, using PRE or Acetone on a surface with Fast Etch will remove the protective coating it leaves behind leaving you with a surface ready to primer then paint.
