I was just watching this video looking for tips on 2 part foam. Most of the micro skiff builders I've seen actually pour foam without the sole on. This dude poured thru holes drilled holes in his deck. Very interesting. http://www.youtube.com/watch?v=gyGBC9Z0g_o&feature=related Anyway, I also looked into AeroMarine for their 2part. Good stuff but you can get it cheaper from Boat builder marine than direct for 1/2 gal.
