Hi ,

I would not bother using Airex for the keels. It is possible to bend
Divinycell using heat gun, or cutting grooves on to it. I recall
Divinycell is 2/3 of the price of Airex here. Sometimes we can buy
second quality Divinycell (variable color sheets) that is even cheaper.
A friend of mine is currently building a Shuttleworth 31 cat from
Divinycell, will ask the current price.

I did not find any price info about Airex.

Regards,

Arttu
