Is this a good price for wood?

[special-K]

What makes wood "marine grade" is all about the adhesive and quality of wood.It doesn`t mean "treated".This plywood in the bed will have exposes laminate edges and that is where the grading makes a difference.
I,personally,would use an oil over a hard finish.I`d rather care for it annually than deal with all the effort involved in maintaining a hard finish.A hard finish loses it`s protection as soon as it is scratched deep enough.The sun plays havoc on it,too.Recoating requires overall sanding and feathering on lifted areas.It`s hard,once surface is interupted,to get the moisture back out and be sure you are working with what is stable as far as the finish goes.I`m a big fan of oils or at least a protective stain.I think I`m going to use a preservative on mine.Then thin out the body paint color and apply as a stain for something different.I kind of want my truck to look unrestored and just good and solid.
I like shiney hard surfaces on wood,too.Not trying to knock it,either.What ever you do will look good.
As far as the width...Without measuring,I`d say 50" may be doable(do-able?)since the side strips will likely cover the inch on each side.
