Why isn't this practice more widespread? Seems a lot less labor intensive. How did you neutralize the acid?back when i used to help build race cars, we sent the stripped tubs for an acid bath. cleans off all the paint, factory seam sealer, bondo, etc. only problem is neutralizing the acid that makes it into various voids and cavities
but yea, manufacturers dip the tubs in various baths for corrosion protection. paint gets applied by robot arms. cool stuff.
