Homebrew PCBs

Try Green TRF by Pulsar pro to protect traces. I use a GPC Creative Laminator instead of a iron but I used a household clothing iron with that etchant to success. A laminator uses the smallest thickness of board thou.

Using plain hydrated ferric chloride etch, warmed up a little, the last two boards done have been really stubborn to etch away the bridges between narrow tracks and pads. They needed extended time , so much that some narrow tracks just disappeared under the resist, and the boards scrapped.
Any suggestions?

Has anyone had success with an electrolytic technique?
