Rem. Model 11 care.
I would replace the action spring with a Wolff. Clean the stocks with a rag that is damp with carb cleaner. Then hand rub in two or so coats of Lin Speed. Leave the metal alone. If you love to shoot then install a two piece carrier for the Browning A5 with a new spring and you don't have to use the carrier release button for every shell. It will load exactly like a late model A5. AND, you will not have to alter the original in any way. Make sure the barrel is in the receiver correctly and make sure the recoil buffer is good. These buffers can still be bought new and installed very easy. You can crack the bolt if things are not set up carefully.
