ZRC 10002 Cold Galvanizing Compound | Single Quart | Iron and Steel Corrosion Protection | Matches Hot-Dip Galvanized Performance | Contains 95-Percent Metallic Zinc

This is the real deal, Its been a year since I painted some steel with this, its in a salt spray environment in WA state, not a single sign of corrosion or even dulling. Follow the prep instructions and it will work.

I have already used one quart of this on outdoor metal items and it works perfectly.I sand the item down to bear metal and apply a thin coating with a small 4" or 6" roller.The roller needs to be barely wet with the Zinc. Squeeze out any extra from the brush or roller into the pan before applying.Just thinly covers the metal and it dries completely within one minute.After that I paint it with regular spray paint or rolled on metal paint.Things you have to do.1) Stir this up a lot before using. All of the "Thinner" material is floating on the top and the metal is at the bottom of the can. You need to stir from the bottom for at least 10 Minutes until all the metal at the bottom of the can is mixed in with the thinner top layer. Stir again every 20 minutes as the metal is always trying to separate out from the liquid.2) This stuff dries fast. You cannot put down a brush or roller for too long or it will start to clump when used. Just make sure all of the metal surface is ready before starting and do everything quickly and in one go.3) Dump the Brush or roller pad after using them. If you try to reuse it the next job will come out uneven.4) Don't put on a thick coating as it will never dry properly. The top layer will dry within 30 seconds and seal off the inner layer from drying. The result is that it looks dry, but underneath it is not.Put on thin coat's and if it's not good enough wait 5 minutes and re-coat with another thin coat.5) I have not tried it but I doubt this will work with a spray gun.

I sprayed a set of skid plats after removing the mill scale and blasting. I chose this product because even with small scratches it should still offer protection to the steel which is more than any paint or powder coat will protect. Water also can't get behind the coating and rust the steel like could happen with powder coat or bedliner/rubberizer undercoating. The skid plates will get scratched after all. ZRC sells the same product in an aerosol can and I plan to purchase this for touch ups.To prep the plates I pickled them in vinegar, an acid. I laid the plates one at a time in a box lined with a large garbage bag and layered paper towels on the top and bottom. I poured 6% cleaning vinegar (bought at the grocery store) on the plates to fully saturate the towels and the following day the mill scale easily wiped away with a red scotch brite pad. I then blasted the plates using the cheapest HF blaster with fine coal slag medium. The scale was completely removed. Surface preparation is CRITICAL!!!I warmed up the can of ZRC in hot water to help mix it. When I first opened it all of the zinc was at the bottom but warming the whole quart up allowed me to mix it up more easily. I put the quart can in a bucket and filled with hot water in my utility sink until the water was at the top of the can.I thinned the ZRC product with one part xylene to 16 parts ZRC (by volume) per the application instructions and sprayed it at 50 psi. I used a kitchen scale (Ozeri ZK14-AB) to get the proportions correct and had to calculate out the density of xylene and ZRC per mL. I think it was 52 g ZRC per 1 g xylene.To spray the ZRC I opened a HF HVLP gun up to 1.9 mm from 1.4. This is the cheap purple gun. I used a wire sized drill bit #48. I didn’t go to 2.0 like ZRC suggests because I want to use this gun for a two-part epoxy primer as well. I set the compressor regulator to 50 psi. I tested and adjusted the gun after filling it.The quart of ZRC covered a complete set of Hefty Fab skid plates for a 2011 Nissan Frontier in two good coats per side. There are five plates in the set. I didn’t measure their surface area to gauge coverage, sorry. I posted a picture of the uncoated plates for reference. I don't have a picture of the coated ones, but just imagine the uncoated ones as light grey instead of dark grey. This was before removing the scale.Seems like it went on reasonably smooth for my amateur hand and cheap AF modified Harbor Freight gun. The surface is hard and the color is similar to hot dipped. I am looking forward to torture testing them as I drag the truck over car sized rocks.

Works good,easy to use and apply.

I've used different brands and types of galvanize/zinc type paint over the years. This is the best. Follow the instructions, apply 2 coats and youll be pleased with the rust resistant this product offers.

Very good coating for protection of previously galvanized steel. This was difficult to mix at first. Easy to apply with a brush once it is mixed well.

Lo utilice para pintar una estructura de hierro que instalamos en una terraza en la ciudad de Panamá que va estar expuesta a las salEste producto lo empleé para pintar soldaduras de perfiles de acero galvanizado hace 5 años y no se ha oxidadoLo estoy utizando además para pintar las parrillas de acero colado en una estufa a gas y ya detuvo el óxido vamos a ver cómo se comporta con el calorEste año vamos a pintar una extrutura en de perfiles ip que se encuentra al lado Del Mar y espero que me ayude a conservarla por mas tiempo sin mantenimiento anualExoente producto y no es caro para la función que cumple

We were given 2 pasture gates from a friend that was rusty on the bottom. We sanded the rust and used this compound and they look great almost like new! I would highly recommend this product!!
