seat rebuild

I am rebuilding my back seats in a 84 2001, due to dryrot, what is the wood of choice. Then once rebuilt do a put a coat of poly on the wood or resin? GB

untreated ply wood is fine and then use resin to encapsulate the whole thing so everything is sealed. You don't have to use resin just depends how long you want it to last. Marine grade plywood really isn't needed and resin will never stick to pressure treated plywood.

I personally would just use a cabinet grade plywood and seal it with resin. The only difference in marine plywood is the glue that holds it together. Wood is wood so if is encapsulated you don't have any worries.

Marine plywood and exterior plywood use the same glue. Marine plywood has no voids internally, that is why it is so expensive.
When I have to use plywood, or wood near the water, I have started using a material called Clear Penetrating epoxy Sealer, available from
WWW.Rotdoctor.com
I have not used it long enough to have any long term results.

RE: seat rebuild

when i rerbuilt all of my seats, i couldn't find a marine grade plywood anywhere. i used untreated exterior. i would not suggest a treated plywood for building seats. the arsenic in the treatment will eat through your staples (even stainless). like the others have recommended, i'd just coat a regular sheet with a couple coats of resin and not worry about it

Thanks everyone, that is what I thought, it doesnt seem as though the original seat bottoms had much of anything done to them, so I think all of your methods sound more than exceptable. I'm reusing the original upolstry, so this will be fairly temporary.

Man that picture looks familiar, I rebuilt all of mine a few years ago. Exterior grade plywood, bisquit joints help line everything up while assembling, stainless steels screws and Waterproof polyurethane glue. Then coated everything with slightly thinned resin and applied some cloth to all the joints. I'm amazed the originals lasted as long as they did because they were not put together very well.

waiste of money using a cabnet grade plywood. The only difference between ext plywood and cabnet is the cabnet has a hardwood veneer so it can be finished/stained so it looks good finished, why do you need that when your just going to cover it up anyway.

Very expensive material to just cover up. Now if you going to leave it uncoversed and stain it then ok, but why have hard seats.

I did not say stain grade. What I was meaning was a good AB grade plywood that is straight.
