Hi Nicamarvin, Please can you give some details of the kind of DIY chemicals you used for your spray on chrome experiment. So far I understand the base coat should be 2K black or white. What do you apply next?, What do you use as an Activator / sensitizer, do you use Stannous Chloride? can this be made DIY?, Silver Nitrate can be made but what "strength" ( % ) is best. Please what is the step by step process?. I have watched your video when you were using hand spray bottles and I was very impressed, I would like to try the same thing as it is not expensive and I will waste a lot of chemicals before I get it right. Please help. Many thanks, Charlie
