aluminum aquaswan

[Marvxyz2]

I believe I may have had some pressure treated wood on my boat floor. and when I heard from this site that it would react with the aluminum I removed it. once the wood is removed is there further damage to the aluminum, or is the threat removed. thanks for any possible info.

Uhhhhh well the "old" pressure treated wood used arsenic (which is poison) and the new PT wood uses copper...... the copper is what attacks the aluminum. Regardless ....yes the threat is gone and be sure to clean up the boat.

Since it's out just replace it with exterior plywood sealed with epoxy or fiberglass resin and some CSM (chopped strand mat)...
