marine plywood

replacing fender wells on trailer need marine plywood looks like prolly 1/2 in looks like there is alot in ill. could not find any over towards gods country

You oughta be able to find treated plywood fairly easy. That stuff should last a long time:ThumbsUp

You might try shutte lumber co in kcmo.
Personally I would try to find 4ply or 5ply exterior plywood. But if you don't care about the texture and color the treated is way cheaper
Good luck on your repairs.

thanks guys cheaper caught my eye
