It is very easy to use a rust neutralizer and you can save you from replacing many household items both interior and exterior. The neutralizer acts as a bonding agent or primer to hold the new paint and also stops more rust from forming.

The commercial grade types for cars are usually applied in a spray chamber with equipment used especially for that purpose. The spray-on type is the most commonly used by do-it-yourselfer and homeowners, and is recommended for mild surface rust.

Saving the iron and steel items around your home such as railings, mailboxes, lamp posts, flower boxes, lawn furniture and countless other items will save you a great deal of money, so it's a product you should become familiar with. They act as a primer to form a bond between the rusted metal and the new paint you will apply.

You may also put an oil-based primer over the latex paint to avoid sanding if it's a big job. She has experience researching and creating a wide range of home improvement and garden projects, and especially enjoys learning about household crafts, cleaning, and organization.

He's written for business publications, celebrity blogs, production companies, law offices, and not-for-profits, and created design fiction for major corporate brands. He grew up in Marble head, Massachusetts in a family of do-it-yourselfer, with whom he's participated in myriad home improvement and landscaping projects‐from veggie garden beds to a full cottage studio.

Now its cracked and starting to show minor surface rust peaking through. I put a 3M disc on it to start taking it down to the bare metal but in places it has some minor rust staining or very, very minute surface pits the disc will not take out.

I've read of using vinegar and water and then rinsing but I'm far from a paint expert. It's a pink phosphoric acid jelly like chemical.

You wipe it on bare metal/ rust and let it work its magic. Neutralize with water after using a wire brush on a drill to remove all traces of rust from pits.

Leaves a phosphoric coating on metal that's perfect to prime over. Off works, brush on.or squirt bottle. Home Depot or lows.

CLR leaves a residue and needs to be cleaned off well before any painting is considered. On another forum, the owner of SPI recently said Off is a good product for this type of stuff, but he also said you have to be really meticulous in neutralizing it exactly as the instructions say.

He says any traces of acid residue left on the surface will react with body fillers and primers and ruin the paint job sooner or later. It's a pink phosphoric acid jelly like chemical.

But etching into a deep pit takes a lot of brushing a replying acid to go all the way in. Off, Naval Jelly, and Rust Mort, among a bunch of other similar products are all phosphoric acid based concoctions.

Naval Jelly) or other comparatively inert ingredients, but the active component in each is phosphoric acid. CLR is a mixture of other relatively mild, but still can be dangerous in the wrong hands, acids.

Here is a link to the Rust Mort page, if you click on the “Tech Data Sheet” you'll see their recommended usage procedure. The ones who did it wrong aren't lying, they just don't know what they don't know, and as a result you get folks who say it works great, and those who challenge that notion.

The kicker with the phosphoric acid products is washing off the residue with water at the end of the procedure. But it's part of what makes it work, and what ensures that repair/refinish procedures that follow will stand a chance of being successful.

Once I was taught how to use it correctly many moons ago I've had great success with surface rust inhibition. Even though most of the products say it won't act as a long term bare metal protectant, I've had, for example.

Bare metal frames sit in the shop for a couple of years with no surface rust development that is visible to the eye. In an abundance of caution I give it another cleaning prior to refinishing, but it wouldn't surprise me if that's not absolutely necessary.............again, depending on cleanliness otherwise.

Do not trust just telling a body shop that you acid treated a car, take a bare shell and HOPE they listened.

A typical paint application will last much longer after an application of Oslo because subsequent paint coatings attach themselves so tightly that moisture and oxygen cannot attack the metal. Oslo is equally effective for exterior and interior work alike and is highly recommended as a pre-treatment coating by leading paint manufacturers.

For best results, use Oslo at temperatures no lower than 36 degrees F. Excessive dew and humidity may prolong drying time and cause powdery buildup. Avoid getting Oslo on adjacent areas such as painted surfaces, concrete, masonry and stonework.

If splashing occurs, flush immediately with water to remove. If taken internally give large quantities of milk or water.

A check should be made by testing Oslo on a small area. Been using Rust Mort for years, I like the thin(as water) consistency.

As has been mentioned in prior posts, complete neutralizing is important, working in small areas at a time and not letting excess into nooks and crannies. Also, good for immersing small (lightly) rusted hardware prior to painting.

Yes I neutralize small areas depending some on the contour of the panel by rinsing thoroughly with clean water, mopping with a CLEAN absorbent towel or squeeze followed immediately with compressed air to total dry. Inside the doors and under the rear windows on my 61 Galaxies have the proper amount of non-through rust.

SPI is some good stuff, I used there 2 part Primer you would swear it was paint when it was dry,had a nice shine He guarantees you can leave it in the weather for 2 years and moisture would never penetrate it, what ever you have left over you can store in a sealed container up to 72 hrs.
