Just bought 2004 Ex that came from Minnesota. Frame rusty with some flaking but not severe (think metal under is solid). Seems allot of members here swear by Fluid Film for frame rust. Others have used chain saw oil and other rust converters. What has everyone found to work the best? I live on gravel roads and question these and dust collection.
Your thoughts?

I too am curious as I am in a very similar boat. I was thinking Ziebart, but I think that would be pricey.

Same situation here. I elected to go with Black Star in aerosol form. I think I'm going to go with a gallon next and apply with a bug sprayer. Black star seems to be working well and living up to claims.

 

I wanted the most protection I could get living at the coast. I cleaned the bottom with a strong degreaser and pressure washer and after it dried applied Rust Reformer. Has held up for over 3 years and the only area where surface rust is present is where the lift arms touch the frames for rotates, etc.

I've got blackstar under my truck and its worked great. Very easy to work with. Tried the bug sprayer as an application medium and it was kinda messy. You need a tip that allows it to come out very fine and the one I used was more like a stream, so it didn't work. I rolled and brushed mine on. Will buy the spray cans next time for the hard to reach areas.

 

I just bought some Corroseal and so far it's looking pretty good. It only cost $52 for a gallon. I slopped it on with a brush and when it dried it was smooth, no brush marks at all. Another cool thing is that it dries clear over a painted surface.

Been looking into this as well. Had been looking at rust bullet but now i see there are alot more options

 

Thanks everyone. Now I have lots of options.

 

Decided to go with Corroseal. I am no where an expert here but what I am finding it seems rust converters that work are basically tanic acid to neutralize the rust and a polymer to seal the metal after the acid converts it. As long as it has these two ingredients, they are basically the same. I went to a few marine sites (boats in ocean water would be exposed to more salt than my truck) and corroseal has very good feed back. Yes it would be better to sand blast down and then seal but I do not want to do a body off restoration. I am going to hammer loose rust off with hammer and wire brush, then pressure wash, let dry and then spray on with Wagner paint sprayer. We will see how it goes. Ordered Corroseal online from Home Depot 1 gallon shipped to me for $57.21.

I liked the blackstar because it goes on a milky white and dries matte black which for me was great because I'm putting it underneath my truck and wanted it black.

 

The Corroseal does the same thing. Goes on white, turns purple, then black. Must be a similiar formula.
