I’ve found great results on interior and above water exterior teak by using Baby Oil rubbed in real well in 3 coats once a year for exterior and every two years for interior. Currently we have a teak swim platform I took down to nude on a Malibu Skier my grandson Cooper and I are restoring. As the teak platform will be often in water... any suggestions as to best product/process for a lasting and good looking finish? – Thanks, Art
