CAN I use it over the rusted trailer frame without any sanding or prep work

yes you can and it will still kill all the rust but you will get a much smoother finish for your final painting if you wire brush the heaviest rust off first.

I have used this product on various projects. To get the best results, you should remove any excess material (loose and flaking rust, peeling paint, etc.). You can just apply it to any rusty spot and help interrupt the rust cycle. If you have too much material over the base/core rusty metal, it may not react to halt the on going rusting action.

You should remove all loose scale with a wire brush before applying. I went over my trailer frame with a wire brush, and a smaller wire brush in hard to reach areas. Afterwards, I applied the rust converter as directed, and applied two coats. I allowed the first coat to cure (about 30 mins., depending upon the air temperature and humidity) between coats. It worked well. I painted the converted surface where it was exposed to sunlight with black Rustoleum enamel.

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.

Answer here...I can't say. I only used the video I got from youtube, and it showed a very clean surface, so I tried to get down to the shiny bare metal. I don't know what rust coverter is or how it works, or what it does. sorry. Luckily we had an electric sander, and it worked like a charm, with a low number pad.

Ospho will convert surface rust to black. You still need to sand and prime and paint

Use sandpaper and a wire brush to remove as much rust as practical. To achieve a smooth final finish, apply the Rust-Oleum with a soft cloth to avoid bumps or streaks. Allow to dry completely. Next, apply several coats of fast drying rust resistant primer. Sand lightly after each coat dries. Repeat until finish is smooth and apply final coat. Be sure the metal is free of dirt or oil before you apply the Rust-Oleum solution. You could apply the finish coat without using primer but several coats of primer will make for a finer finish and the final coat of paint will last longer.

Yes, I use it on small rust spots all the time and there is no need to sand first. I just wipe off the excess; it hasn't ever affected the surrounding paint. It will leave a film that can be easily wiped off. It works great. No need to use primer, just paint right after it drys.

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.

I used it on both rusted areas and non-rusted and it worked well, but it was amazing on rust. Covered the rust and really protects well. I actually painted under a trailer and through mud and rain it holds up great.

Use the metal prep. It will then adhere nicely to rusty and non rusty metal as well as painted surfaces. I used it on my 68 Cougar and it was awesome. I also used the por putty after I used the metal prep and there was no adhering issues.

Take some high grit sandpaper (400 wotked great for me). Wet sand it. Try to remove as much rust as possible. You are going to primer the piece with high heat primer. Worth the investment to do it right.

not unless u completely seal the grill. If you want to prevent rust on a grill, season it properly. Scrap it clean, no rust showing, coat everything with oil, then burn lots of wood chips threw it until its covered in a thick black tar. Then just make sure u clean all the ashes out after every use, ashes are alkaline and will eat through metal, plus they hold moisture which then rusts what it doesn't eat through

There's no reason to remove it. If you feel you must then go ahead with any technique already mentioned. You'll find however, the coating also hides the tooling marks. To remove this you will need to spend a few hours sanding and polishing. You'll then need to keep it oiled. There are different thoughts on this so I will refer you to YouTube to make your own decision on how to finish it out. The coating on mine has lasted a couple years of use and no rust issues

I used it over Por Putty as a sealer ..I have not tried to sand it but would think it would be sand-able.. with something like a demel but not by hand.. the stuff is like black tooth paste and like the por putty will dry hard..being paste like it spreads very easy, so not much sanding was needed..I hope this was a help

No. But the rustolium paint and primer spray cans would do a pretty good job. I painted a 21 foot aluminum boat with it and it looks great.

Yes. Just make sure that you rinse it off and dry it when you're done. The water will oxidize the metal and cause it to rust if you leave it wet outside of the water.

Yes but it will start to rust from frequent use. The frame is painted steel. If you are looking to salt consider a spreader with aluminum or stainless steel construction. (Otherwise be prepared to wash this spreader or use fluid film to increase longevity)

The legs and cross bars are all aluminum with canvas fabric so no rust there. Only metal parts are the pins holding the joints together. I would spray the joints with plasti dip or rubber spray before I left it outside. And the canvas will rot after a few years of constant sunlight. You may want a plastic chair. This chair is better suited for throwing in the truck or camper after use.
