I removed the paint from this wood, the top ring of a raised garden. While scraping I got to a soft part and easily removed this rotten wood, creating the hole in the pictures: it is 2x2x5"
Should I fill it completely with one of those things they sell to fill wood holes? is it too big for that? should I just fill it or first use the liquids to "harden" the wood? should I just spray it with something and keep it as is (it is kinda artistic, so I may go with that option, as long as it will not cause it to become worse faster).
if filling it, is it better to fill it with actual wood first and the rest with the filler (instead of wasting tons of filler?)
Lastly, will I be able to stain the wood, or since it will be a mix of wood and whatever filler I use, stain will not look good and I need to paint?
should I just remove the 4 woods (all 4 sides) and install new ones (all 4 so they look the same, not 3 old and one new).
