Failed to notice that you said 3mm. I have used both 4mm and 3mm of Joubert. Both good. Compared to some Israeli made 3mm that I got once that was actually 2.7mm and had thin face plys, the Joubert was a good 3mm+ and had full 1mm thick face plys. You could probably get by with this, but check and make sure they don't have 4mm too.

: The price is great for a local supplier.

: Are you using the 3 mm because its the only thickness you can get or because
: some other reason?

: While 3 mm is lighter, it is also more flexible and has thinner face plys
: that are easier to sand through. It does make a lighter weight boat
: though. I built a boat with 4 mm hull and 3 mm decking....
