Rust on frame ?
Besides sandblasting what have people done to remove the rust from the frame before putting on epoxy? What is the rust remover chemical that work the best? I wire wheeled 90% of it off but, would like to treat the spots that can't be hit by the wheel.
Thanks,
Danny

Sand blast is easiest. Chemical dip will get the inside. You will need to treat the inside after though. I used POR15 on mine but there are several rust encapsulation paints available. Epoxy is good but POR is better, that stuff is very tough.
You can get a spot blaster from Harbour Freight pretty cheap to hit the small areas left if you have it 90% already

No, I just want to check to see if there are other options. I have the Eastwood pressure blaster but I need to work out the kinks in it. Clogging issue in the tip. (Media properly too large). Just curious on chemicals since there are so many vendors which one really works if used.

Hello my fellow Vettemod friends! @ Dennis, I have 40 mesh Black bueaty in the sand blaster. Eastwood said to go to 80 or 100 mesh.. What grit size did you use? I don't think moisture was the proplem since it didn't work from the start. I'll figure it out this weekend. But thanks for the reply

Don't know the grit size, you should ask 1Michel.
At the time his system was kinda rough (DIY), and adding a water separator was one of the best improvement against clogging.

I had my frame dipped in a non-destructive electroylic bath, then dipped again in a zinc phoshate tank. Cost was $2000.00 (stripping was $1200.00 and the coating was of course $800.00). This included the frame, tranmission and fuel tank crossmembers, plus the frame extension. As mentioned, dip stripping gets inside the frame rails; areas too difficult to reach with sand.

Chelating process (molasse) is also very gentle with non rusted metal.

Weld it after sandblast
If you would like to 'tighten' up the frame, have the seam bead welded the entire length on both frame rails.
The frame rails were only welded about 8" apart down the length originally. A full length bead will stop any flex.
Good thing to do after the sandblast/stripping before you epoxy.

By the way with the Molasses method, be prepaired to have stuff growing in it when you're done. The mixture can be dumped as it's Bio degradable.
For A arms and springs, a 20 gal. drum setting around works well.
