These pics show the end result after totally filling the hole with resin and then a quick sand to remove the rough edges, once the fibreglass had hardened.
I used a small file and a screw driver to press down that loose trace as the resin was hardening, so that I could sand back the fibreglass without totally destroying this trace.
The credit card piece and sticky tape came away easily once the resin had hardened a little, and left a nice smooth fill.
I re-drilled the two missing holes for the transistor.
(Note the special increased spacing and wobbly allignment of these holes...er, to aid with heat dissapation
)
I needed to clean up a couple of the solder pads that had resin partly covering them but this was fairly easy to scrape off.
Anyway I'm pretty pleased with how it turned out and hopefully I can remount the transistor easily now.
I haven't actually tried soldering to this area yet but will let you know how it goes in the next couple of days.
