I have a wooden front door. I am not sure what kind of wood that is, but my guess it is walnut or alder. The guy at Kelly Moor paint store suggested me to use a Marine Valspar to protect it from the weather. After 3-4 month, it turned yellow and we really disliked it. Then I sanded down the door and stained it again and got it close to the original look.
What can I use to protect it? I don't want its color to change significantly. It is covered by a porch and not exposed to direct sunlight for most of the day. Rain doesn't get directly on the door either. I live in northern California thus the weather isn't as harsh. Would Tung/Linseed/Teak oil work for this? I don't mind having to rub it on once a year.
To stain I mixed Danish Oil, Cabot Clear 19200, and color pigments. I used paint thinner and the same color pigment to make the shadow. May be, I can put a coat of Cabot Clear by itself?
Thanks much
