Absolutely horrible. I dont recommend it to anyone doing such a large piece as the grill or deep as the headlight bezels.
Gave everything a good sanding.
Went to target and got a plastic bin that would hold everything and filled it with 4 or 5 gallons of clorox bleach.
I noticed a reaction immediately. 4 hours later I could no longer smell any bleach or see a reaction going on.
There was a decent amount of discoloring and some new flaking going on, plenty of black sediment.
Round 2 I decided to go get my bleach at the dollar store. 1/2 the price and seemed to be twice as strong. I dumped 6 gallons in.
I let it sit over night. There was still copper and chrome left all over the grill and bezels. It looked absolutely horrible.
So i figured why not go for round 3 and thats where most all the plating was removed. To get rid of all the bleach "properly" I took it to the local waist disposal place. The ENTIRE cargo area was filled with bleach containers.
After all that I spent an afternoon filling/gluing cracks and sanding by hand to even out the specs of copper left over.
Relatively so much time and $ spent to remove the chrome, my OCD set in and I didnt want to have to sand and paint in the future.
Probably wouldnt do it over again tho.
