    I used to have fortune in my login script.

    Well, I work up this morning (that is a good thing) and my right sinus is sort of plugged up and sore. I had a paint respirator on last night as well, mind you I have 3 kids, could be anything.

    kchriste, be careful with that stuff. I might try a board with it today. But the ferric is much safer to me. It is messy on a spill, but thank goodness I did not spill the HCL, hate to see what that would do.

    In a pinch and if you have a good working procedure it is probably OK. But I think it is a lot more work, costly and one mistake could be very bad.

    You bet! I kept a couple of buckets of water around when I was etching just to be on the safe side.
    Ferric does appear to be a bit tamer than HCL, but it was interesting to experiment...

    I put 3 small 1/2 full eye droppers of it in 4-5 oz of water, and shot it on the concrete outside and it foamed up and figured, ferric cholride works for me.

    No reason to screw it that stuff :) My nose is still a little stuffed up.

    When I hit it with the hose it was neutralize pretty fast though.. But I did not like the smoke last night and the fizzing today.. Stuff is strong for sure and it is 43% I think..
