Hello all: I have not made much progress this past month, but am getting ready to start to do some wood work. I have G2S Baltic Birch plywood and am looking to find the best finish for it. Reading the posts from Oldsledz, I undersand he used Sikkens #085 Teak finish on the interior followed up with 3 top coats of marine grade varnish. So, I have some questions for Oldsledz...I obtained a sample of this #085 Teak from Sikkens and like the way it looks. However, I contacted customer service at Sikkens and they do not recomend using anything but 2 coats of "Cetol 23 plus" on top of the "Cetol 1 base" to allow the wood to breath. Also, this Cetol 23 topcoat provides for more of a satin finish than a gloss finish. They also do not reccomend using any type of stain on plywood, so I am a little skeptical of all of the information they are providing. Please let me know how this finish has been holding up for you.
Also what did you do differently on the exterior? Did you use a different base stain and topcoat combination or do the same? Any info is much appreciated!!
