I purchased a 71 Catalina 27 footer and it needs lots of TLC. I have been sanding and sanding..... etc, and now have started some Teak finishing. I have just learnt the hard way not to use the usual wood putties - even if they say they take a stain - as they won't. Fortunately for me, the areas where I used the wood putty isn't easily seen, so no hissy fit on my part.What do people use to fill holes (like from screw holes that are no longer used) when refinishing interior teak and other woods?
