E2K13 has used it on his shin tools, I have used it on my armor and amd starting on my bucket with it...its GREAT stuff! Granted, I haven't put the top coat of paint over it yet...but I'll let you know how it goes...
Once you put the metalizer on, you need to buff it with a paper towel (it gives it that brushed metal look) then put the Metalizer Sealer over it...THEN the paint. 
I'll get my butt in gear in the next few days and post some pics.
