I’m looking at the tech sheets for this and it doesn’t say what bare metal needs to be sanded to. Anyone know? Also has anyone used this and is it any good?

That was my question. I sanded it all the way with 80 grit on my buffer/sander and went back over with 180 on my DA. One of their other epoxy’s said 80 then 180 so that’s what I did.
sorry my bad lol ,i would always suggest the roughest grit possible that the product will cover usualy on steel i would use 80 grit but even 180 should be good enough for a physical key
I prep bare metal with 80, and feather edges with 180
