trim finishing hammer

Got the 90% Sodium hydroxide pro strength granules at Homie Depot and went to work. 6oz/gallon as your instructions (9oz/1.5G in my case) and set timer for 45 min. Damn things went crazy in that mix so after 17 minutes I pulled one out and had a small burn through where some corrosion had already pitted it deep so I took it out, rinsed it and set the next bezels timer for 8 minutes and that was about right for 65 Valiant bezels anodizing. YMMV.
<<Use doubled up nitrile gloves and a respirator or at least a mask and glasses when working with this ****! use a fan or STAY UPWIND! Don't do this inside....vapors are nasty!>>
