Being as how you guys are down under and might be talking about the same stuff Im thinking of i'll throw it out there anyway.

I used some stuff called "Caviseal". It is finely ground fiberglass matt...ground into a real fine powder. Here they use it on boats and what not to bond the hull to the deck and so on. You mix it in the resin before you put the hardener in...for example. you pour out 4oz of resin, mix in your Caviseal and make it to the consistancey you want(thick paste or runny). Then mix in your hardener according to manufacturers specs for the resin(12 drops per oz)

The resin alone will bond the panel but might have tendency to crack under stress. The Caviseal adds some strength and flexability. I would suggest washing the steel with vinager and then drilling some 1/16 or 1/8 holes about every 2"s or 5cm...lol...around the frame. The holes will allow for some really serious bonding.

just my thoughts.
