The 1st etch with PLA pliers was successful in that it was a lot easier to massage a large board, but unsuccessful in that there were still air bubbles & the pliers absorbed acid between the laminations. The acid leached up to the handle through capillary action. Washing them in hot water deformed them.  Those right angles were hard to clean & splashed. Would be best to dedicate another pair just to the acid stage & add some curves.
