I did mine on my own in the dark...it was the first time I did it and hadnt thought it through! Was more difficult on my own and took about 3 hours!
If it sticks to the wings, peel it off slowly with some heat, dont yank it off when its cold like I did, it can pull the laquer off...
With 3 people it shouldnt take long at all.
Once I had finished I took the bonnet off, turned it upside down and neatened the edges, I heated it up, stretched it into the crevasses and trimmed.
Looks good though, lots of people have asked me about it...
