thanks dean & mike for the quick replies.

still got a few questions though, if i may. firstly, i'm not familiar with balsa-right and wonder if it's available in australia or if anyone knows of an australian equivalent?

it sounds like you only use 1 coat of finishing resin, not 2 as other methods seem to specify?

also, do i need to wait for the resin to cure slightly before i go at it with the micro balloons, or can i get stuck in straight away?

thanks again, will be looking forward to any photos of the process you all may have.

cheers, dave
