Plywood?

[tsubaki]

This is the best plywood I have seen for staying together.
Problem is, the coating on it makes resin almost impossible to stick.
A vigorous sanding will help.
This plywood used to be coated with an oil that had a diesel smell to it, now the coating resembles a wax of some type.


And Stinks right, don't use treated. It's not just the fact nothing will stick to it, the glue will seperate in the layers.
The cabinet grade stuff Skools is referring to is lighter and more rigid (requireing less support), would be the best bet.

In my younger days I done a whole floor in a small boat in PT.....I was NOT happy about a month later...



Ive used regular sanded pine every since....never had a problem..

I've use doug fir marine plywood a/b. It's about $50 for a sheet of 1/2 and $65 for a sheet of 3/4. Also if you can find MDO (what's used for billboard signs) that is a little less and very good quality usually no voids (comes with 1 or two paper faces).

Sometimes you can find a sign supply shop that will sell you old bill boards for $10 a sheet 4/8 3/4" MDO. I bought 15 sheets from a place at $5 each to do shelves for a friends garage.

Well i checked with LOWES today, and there lumber looked HORRIBLE! Even there cabinet grade plywood had knots in it. So I ended up going to HOME DEPOT and got a sheet of 3/4" sanded ply and had them cut it to size for me on there big saw. For $38 I got a nice piece of ply with NO knots in it, and had it cut to size as well. Hopefully it works out. I'll start another post with progress pics.
