An excellent aluminum and carbon structural adhesive for catamarans is Araldite 2013 made by Ciba. This is what Marstrom uses and what many of the Tornado sailors call Marstrom "grey glue". Marstroms price may seem high but I think he is selling it for about his cost.

Ciba glues are very expensive in the US because of the shipping. I normally use 3M DP-110 or DP-120 which is similiar to Araldite 2013.


Keep in mind that these glues are very expensive if purchased in small quanities from the maker ($15-20/50mL). There are internet sites that sell them but the prices are still high. Try to find local companies that uses large quanities and is willing to resell some. For example when I worked for Lockheed, I could buy 3M adhesives at the Lockheed price. I remeber paying $20 a case or $2/50mL.

All of these are good adhesives and there is a lot of experience in using them so you know how they will age.
