Ok I take that back. Too long in the bath (30 minutes at 1.5 volts) and I got bubbles and streaks in the plating. It looks just like bubbles formed on the surface and then left marks as they grew and traveled upwards. I think we don't see marks when plating at 5V because the bubbles form and dissipate so rapidly. However apparently there is danger of Hydrogen gas buildup when too many bubbles are being formed. So... commonly platers will use the same lower voltage mentioned and use an agitator/bubbler to prevent bubbles on the part and still be able to get a thick coating. I think we are fine as long as it's done with adequate ventilation aka outdoors.
Luckily, a minute in the acid bath and all the zinc is gone!
Here's my electrolyte anode setup. I used anti-moss strip meant for putting on a roof. I had to buy about 10X as much as I needed, but it allows for good coverage.
and a new front wheel spacer zinc'd. Looks awesome.
Whymee you're the man for posting the DIY! Thank you so much.
