Building A Floor For Aluminum Fishing Boat Prefinished Stair Treads - Should I Coat With The Same High Build Satin Polyurenthane As The Risers?

Prefinished Stair Treads - Should I Coat with the Same High Build Satin Polyurenthane as the Risers? - building a floor for aluminum fishing boat

I bought the liquidators of prefinished wood surfaces, but used red oak unfinished strip for the side layer. I installed red oak flooring for the protection of aluminum oxide. These limited measures do not seem to have the same layer of aluminum oxide. Then I pushed too superior polyurethane durability Built To add or not successful, because in painted wood?

Thanks
