[QUOTE="BassBlaster, post: 217679, member: 2865"] This particular plywood was discussed in depth recently. The conclusion was it will still corode aluminum. Not as fast as typical pressure treated lumber but it will still corrode. Manufacturers use this stuff because it is labeled as "safe for aluminum contact". My guess is it still wont last as long as exterior grade ply with Spar Urethane coatings. It would cost manufacturers more money to treat regular ply so buying the product your pushing is cheaper for them. Still dosnt make it the best option. Edit...Okay , I was wrong. I guess I should have clicked the link before assumeing it was the same as what was recently discussed. So they claim this has arsenic in it rather than copper so it wont corrode your boat. Insted it will just kill you, lol. There is a reason the EPA banned that stuff years ago. [/QUOTE]
