Just got done etching the garage. I always heard about how bad the fumes were, but really it wasn't too bad with a fan on and the garage door open.
I basically bought a flower watering bucket. Filled it up with water and added the etching acid packet to it. Evenly applied it to the area to be painted. Let it sit for about 5 minutes. Then used the hard bristle brush to scrub it in. Let it sit another 5 minutes, then pressure washed it off, followed by squeegeeing. It's air drying now. If everything seems good, I may paint it tonight, or tomorrow.
Couple pics showing the acid going into the flower watering jug. Then a pic of the half of the garage wet with the etching acid soaking in for a little while.
