I want to still prime the rust on my metal roof before using this, any suggestions on a rust primer before using this please?

I would recommend contacting the manufacturer? I have only used it over existing EDPM roofs after washing it good.

Hello Bill, To use any primer or paint, you have to clean the metal. Most new metal has at least traces of manufacturing oil on it. This will ruin your paint job even before it's finished. Clean the metal with a strong dishwashing liquid and rinse well with hot water. If you don't have compressed air, at least get as much water out of the inside as possible, then dry off the tube with a clean towel. The make sure that the first inch of the inside is dry so the paint on the edges is not affected by water. Then Prime. The thorough cleaning is very important. Hope that helps! Joe

what i did was grind down all along where the flare would cover and painted it 3 coats of primer 3 coats of paint close to match my original color and then took new oil and ran it along the new paint work and inside the rust holes after the paint dried obviously and then installed the flares. its been like 6 months and no rust is spreading so i hope it workes

To be on the safe side, I would clean the sufface with TSP, and then use the primer. I would also use a hard bristle brush during cleaning, to remove any loose sealants, or coatings. Be sure to caulk around any roof vents before application.Hope this helps.

You should sand down the rust and try to cover it with Bondo, then sand that down before trying to coat over with the coating. Rust may eventually come through the coating.

Since neither one is a magic bullet - i'd go with about the same. I cleaned and sanded the area and applied twice. It says it doesn't effect the surrounding area which isn't entirely true. It slightly discolors it. I feathered it out and it isn't as noticeable. It did cover the rust and dry with a black primer coat which quickly rusts again if you just leave it exposed.

I agree with the previous responder. I would be careful using something that aggressive on the finish. Have had great results with Bar Keepers helper when nothing else worked...particularly around rust.

This stuff is great for bonding/preventing rust. I have used it for more than 40 years. When you applied it to rust, it will bond the rust to the metal and turn black. Now with your question, I presume we are talking about steel doors, right? First sand the loose rust off, apply Ospho directly to the remaining rust, let it sit till it becomes black. If you want a smooth door, sand again, apply sopho again, it will act as a primer. When dry, paint to taste.

use primer before installing liquid roof. Next day put a thin coat of liquid roof, them wait 2 or 3 days before putting the second coat and them you are set for 10 years or more.

I'll be honest with you. I have never tried it but I'm sure it will work. All its doing is neutralizing the rust so it can stop spreading.

Yes, this is a primer and it is intended for that use as well. Rustoleom actually advertise to do this on the packaging. Simply apply at least three coats of the primer (in a very well ventilated area, it's an oil base primer, and stinks - lots of fumes), then 4h later apply the chalk board finish. That's what I did on a wall of my kitchen and works very well

Hi Nathan, I agree with MOzarkian regarding the spray. I'd make sure to cover the entire piece, front and back well. I live in Florida, and we too decorate outside walls......clear sealant is my best friend!!! You might have less issue with rust as where you are it is a much drier climate.

No, not unless the rust is removed, primed and then sprayed. I used it after sanding, a bonding, priming, matching the paint and then the clear coat. It might help over a fresh scrape. once there is rust, it has to be repaired. Hope that helps.

Yes. I would definetely recomend Rustoleum self etching primer. Worked great for me!

its been with me for almost a year now. i made my own cover. things are fine with me, no rust. i reccomend that you make a thik cover to prevent it from heat and rain.

I guess I should have answered "Don't Know". I know on my application, that was was meticulous on surface sanding and prep. However, if you are dealing with metal and moisture can get to the metal, you are going to get oxidation which will start the rust process. Hopefully, someone will have the answer for you or you may have to inquire with the manufacturer, The GB Weld Company in Texas. Sorry!
