[spareparts]

never had any luck getting resin to stick to treated, just allways used forming grade playwood, its one step below marine, they use it to form concrete, sometimes you can find it at the super stores, usually has a red paint on the edge, can't remember the official name for it, but its exterior grade with a B/C finish. I allways thin my resin with acetone, you can go up to 1/4 acetone before it will cause the resin to not kick, you will have to mix it a little hot, the thined resin will penetrate the wood, giving a better bond, next time you have some uncut resin sitting around, mix it and paint a piece of ply with it, wait till the next day and smack it with a hammer, it usually will pop off in chunks, not what you want on you're floor
