Hi everybody,

I wanted to post this up, because this is a great product. Evaporust gel. My son and i have gotten started on his 69 Barracuda, and a previous owner had sanded bare metal stripes and spots in several of the body panels, then left them that way. I bought the car and it sat another 5 years that way. Its in a dry climate, but even so rust never sleeps.

I have used regular evaporust before. Good product. Comes in 1 gallon containers at oreillys etc. Pour it in a container, submerge your parts, several hours later they are clean. The product can be reused hundreds of times before it needs to be disposed of. Its apparently non toxic and biodegradable. Rinse water is used with trisodium phospate mixed in (avail. at lowes paint department)to prevent flash rusting.

The gel is a bit different. It has the consistency of snot, i tried this on a really crusted up spot on the door without any sanding to prep it. Just brushed it on, and covered it with plastic against it to keep it in place and prevent it from drying out. They recommend checking and removing it after 2 hours.

After 2 hours i wire brushed it and rinsed it off. I could see progress, so i reapplied and recovered, and turned in for the night. I cleaned it off in the morning and saw more progress so i added more, covered it up and went to work. When i got home, and cleaned it off, i added more and left it on one more day covered with plastic. When i cleaned it off the 4th time, i was left with clean pitted metal. I looked at it with a magnifying glass and could see to the bottom of the pits. I cracked out my DA sander and sanded off the rest of the paint in this spot, and wiped everything down with a TSP and rinse water solution to coat the steel and prevent flash rust until i can get some good primer on it.

I think this stuff works great, i do recommend sanding the thick scale off first before using it, since you wont need to reapply it so many times. Sandblasting does work but cannot remove corrosion completely in small pitting so the rust ends up continuing to eat. Plus if not done right on sheetmetal panels, sandblasting can warp the metal

Heres pix in chronological order
Hope this helps
Matt

Remove all that old paint to bare metal before etch. Not only is it a poor foundation you have compromised it's crappiness even more with the chemical.
