really made a breal through on home zinc plating, first of all i blast of old zinc with shot blast but glass beads not steel shot, small compressor and a shot blast gun, results are great clean bolts clean metal, then in the zinc tank, MAKE SURE you agitate the solution and tap your items about whilst zinc plating, or better still get a small pump which is normally used for fish tanks, or just stir on a regular bases, sounds like your cooking but intheory you are cooking metal, the reason for this is to shake air bubbles of and keeps the solution moving and mixing therefore getting a good plating, this is a must please note last, when plated for about 45 mins MAKE SURE you rince of with clean water well, then you can dip in the required colour passivate for about 15 seconds, i swill my aroung whilst doing so, then hang to dry for about 8 hrs before touching with fingers i leave mine for 24hrs, hope this helps home zinc platers as its real consistant now see photo.
