I was reading up on wood for outdoor use and found that white oak seems like a suitable wood. I was also considering cedar. I just wanted to verify it with you guys. It would be for a grill cart that will be kept under a grill cover but stored outside so I don't think it would be directly rained on.
white oak is a perfectly acceptable wood for outdoor/wet use. A lot of the low-boy heavy equipment trailers are decked in white oak for the durability & strength. I rebuilt some boat seats using white oak and marine grade ply, the white oak stood up better then the marine ply...
If I was making an Adirondack chair these days I would make it out of western red cedar construction lumber available at home centers. For screws, I would use rust-resistant deck screws and cover the screws heads with glue plugs. Glue to be poly. Finish would be two coats of exterior oil , or, use clear wood preservative such as Wolman Raincoat Water Repellent in a tint = Cedartone.
