Designed long tanks for spar conversion coating. Using darkroom trays for smaller items. Being VERY careful using this material. Thick rubber gloves, 3M purple respirator, eye protection. No splashing, drips allowed on floor/counters. Mixed 5 gallon batch at 85F, temps drops quickly in trays, will design tray heater from heating pad and beer fridge thermo control. Used acetone to remove marks/glue etc from sample parts. Washed in Dawn dish detergent. Rinsed. DEOX B is phosphoric acid etcher, 3-min, as I used a 1:3 ratio then water rinsed. Kept in rinse water until ready to drop into Alodine tray. First sample item was waaaay too converted after 3 minutes. Finally found 1+30 optimum even with tray cooling down. Will added other samples pictures later (on road trip)
