Hi Malcom,

Thanks for the addresses and tips - will bear that in mind when i get to the painting stage.

Spent an hour tonight sanding down the glass then filling it using P38 (bondo for US types) followed by more sanding and then another layer of filler. I've got the shape is the leading edge back so now its just a case of filling dips and lots more sanding.

I've learnt two things so far using the filler.

1. Don't put too much catalyst into the mix, it goes off far too quickly!
2. Wear my respirator in future as even though it smells pleasant it lingers for far too long and gives you one hell of a light head.

Cheers,

Colin
