A rusted panel like that, I’ve found POR15 metal prep works very well. The POR15 coating a moisture cure urethane I can’t endorse... its junk. Spray it on, red scotch brite, keep it wet for about 15 mins. Rinse it off. Repeat if needed. It’s phosphoric acid based and leaves a zinc phosphate finish that can be left open for a duration. Any small pits like in your video can be sealed with epoxy primer. It can’t breathe or get moisture, it won’t deteriorate.
That POR15 metal prep sounds like eastwood's afterblast. Phosphoric acid and leaves behind a zinc phosphate coating. Interesting I might need to try that out.
Interesting, I’ve always been using fertan. Might be a Europe only product. But this stuff seems nice. I’ve also seen some videos about phosphoric acid? But I haven’t tried it yet.
Good to know. I’ve seen people use vinegar and it turns out great. I was thinking about using the gel for vertical sheet areas. What about flash rust? Did you have primer ready to go? Thanks for sharing
@jimdrechsel3611 yes we primed it pretty much immediately, I plan on doing another video on metal treatment. Especially in SC humity you got to be fast with it.
@jimdrechsel3611 we originally stripped it with 80 on a da and we even tried to grind some of it off with a roloc disc (you can see this in the video). So i'd say it was pretty much prepped with 80g. The rust you're seeing is after the da with 80.
East wood do rust etch, rust converter and rust dissolver. The rust dissolver is for the heavy rust on chassis. The rust converter is there for surface rust on panels. The rust etch is also designed for panels if its not too heavy. They have a good video here...let you decide what the best for the kind of work you need it for. ua-cam.com/video/DLUmVMLlcz0/v-deo.html I want to see how the gel works compared to the liquid on serious corrosion, but looks like good stuff anyway. Krud Kutter appears to be the fastest acting liquid dissolver (soaking). For the gels I am trying to gauge the difference between rustoleum, naval jelly and the eastwood option.

I've used rust mort from SEM in the past, but it's more like a converter. (phosphoric acid base).

@@lowcountrylowdown9000so you roughed the surface to accept primer? Like 220? 360?

I'd like to find the best one myself for thin panels that you're trying to save. something that you can't blast.
