Re: Flash Copper
I sympathize. Well it looks like you got the first part right but Idon't understand why you tried to sand off the first layer. I would suggest using 0000 steel wool after the first acid copper. Clean and acid copper again 15 min. then rub down again with steel wool. After the third coat you can start to use 400 grit sandpaper. I keep the plating down to 15 minutes to avoid the porosity which is inherent to acid copper. Personally I then transcend to 600 grit and 1200. At this stage the copper will buff like a charm. I prefer to spend more time sanding then buffing.
