Where can I find marine grade plywood

[Hlleonard]

Thanks fellas'... I'm not sure which I will use, I have read about the glue not wanting to stick to the pressure treated but that might not be a big problem, The major stumbling block so far with the pressure treated panels is the quality of what I have seen, If I can find some treated that is better quality I will probably use that but it at least has to be flat without the voids in the surface... I repaired the floor in a bass boat a few years ago and used the pressure treated and fiber glassed the surface but I don't remember it being as bad as what I have seen so far.

Pressure treated does bow a bit. Peter had a post about pressure treated wood and aluminum a while back. Seems he had some issues with it if I recall correctly. LK Tapp and son's has it in Elizabethtown. Last i priced it was $90 for a 3/4 4x8 sheet, however you cut it you have to seal cut edges. And it is heavy.

Please do a search on this board for pressure treated plywood and aluminum or google pressure treated plywood galvanic corrosion or something like that. The wood asociation does not even recommend putting today's treated wood on contact with amuminum siding on a house-- it contains less arsenic and a lot more copper since 2006. Copper + aluminum + water = electrical charge that eats holes in aluminum pretty quick. I would not get today's pressure treated wood of any sort any where close to a an aluminum boat including carpet trailer bunks. I presume your boat is aluminum?

I would look into some of that vynil flooring that looks like carpet that they are using in some of the newer boats as well..
