In the mean time managed to vacuum the first DB carbon on the ruder blade. Temperatures were around 10-12ºC and had to use a make shift heating chamber to get proper curing. It came out just great. I just hope next layers (UD and final DB carbon) come out just as well. Right now weather has turned very cold and most of the time wet too so I keep on fairing until an opportunity shows up to resume vacuuming de ruder and dagerboard.
