Wondering if you guys have any information about Treated plywood reacting chemically with aluminum, causing it to corrode. I am redecking my 16 ft fishing boat and wondering which type of plywood to use. Others have advised against treated, due to the above mentioned worry. I figure I will use BC sanded 5/8 (actually like 17/32 which in my math class was barely over 1/2 inch). I am thinking of coating it with "rhino-liner" type material for grip instead of using carpet.

anyone have any suggestions? Should i use marine grade plywood? Cost is almost 2x.

Hum, that is a good question and I am not an expert on the subject.  Without the Rhino Liner I would save my money a little longer and when I had enough, get the marine plywood.  It would seem like the Rhino Liner material would make a big difference in sealing the cheaper  wood.  I have Rhino in my truck bed and like it, but it does fade sitting in the sun.  If it were me and I decided to go with the Rhino, I would seal both sides and probably put a second coat on the  seams.

I've never heard of the treated plywood reacting with aluminum, but I guess it does make sense since the chemical used in treating the plywood, gives it a heavy salty residue.

All plywood is made with outdoor glue, there's no such thing as plywood laminated with indoor glue, that much I know do know. So in actuality your not gaining a whole lot by wanting to use the treated plywood anyway.
Use regular CDX, or BC as you mentioned and seal it up.

You can use regular plywood. After you put it in, get a quart can of that fiberglass resin that has the hardener in the lid. Mix it all up. Then use a 4" paint brush to cover the wood with it. I use two coats with a cureing time after the first coat. It will seal and waterproof the wood so that it dosen't rot. After it cures, you can put any kind of carpet or other covering on it you want.  It will last for many years.

use aluminum, it's a lot lighter in weight.
