Hello everyone last fall I refinished all the woodwork on my boat. I removed all the woodwork from the boat. I cleaned the teak, sanded it down and applied 4 coats of Cetol Natural Teak and 4 coats of Cetol Marine Gloss. My question is do I just wash the woodwork and apply 1 coat of Marine gloss or should I use a scuff pad scuff it up and then apply a coat of Cetol? Also I did the same to the interior teak is it necessary to put a maintainance coat on the interior every year? Thanks in advance for your help.
