what have you wrenched on your bronco(s) today?

I was told that the acid dip process would remove every contaminant. So I didn't waste too much time on it other than adding overlapping welds and a brace. They took the frame and then came back saying they left in the acid bath longer to help remove the dirt and grime that has built up over the last 35 yrs or so. Well when I looked at it in person it looked like a painted boat trailer that's been sitting in a marina on Johns Island for 30 yrs! Well, the galv coating doesn't stick to weld slag, thick paint or undercoating. They said initially I should have had it sandblasted before handing it over to them. Where ever there was a contaminant there is a cancer spot (zinc oxidation buildup) that looks like rust and then you have blotches where the galv wouldn't stick such as heavy grime and paint (see pic). So now instead of buying $100 in KBS paint I'm gonna spend $250 to have it sandblasted and powder coated. Chris (owner of Stuyck Co) will spot blast the cancer spots as well as many of the other uncoated spots. I will pressure wash the spots that has flaking which is leftover paint and grime that sandblast won't get off, plus I got to remove galv drips. Chris will not remove all the galv on the outside, if its good then its staying. Once he feels all is good he will lightly sandblast with shells to prepare the galv surface for the Powder coat. All I gotta do is decide which color and finish. The inside of frame looks awesome, it's all silver white and you can see far in there unlike before. The KBS system would require a lot of labor and man hours, plus the $100 to buy. For $250 someone else does a majority of the work and I get PC over a galv coating which I didn't think you could do to begin with. I'm so ready to move on to the next step!
