Hi Andrew!
For an normal scrubbed etch time of 1min for 1/2oz and 2mins for 1oz copper, it took you 15-20 mins to etch your board? What were you using for etching solution ..... "chicken broth"??? : (
In trying any new process, most of the mistakes are made in the first and early attempts, you may want to revisit this method as it address many of the objectable issues by other means.
