I have large connecting patches peeled off from an interior window sill. It was some kind of hard chalky layer underneath its wood. I have already used 16oz of wood filler of DAP Plastic Wood but it turns out I need about 32oz more. I am now looking at joint compounds in powder form and not sure if it is a good choice. I will be painting over it. Can you recommend some kind of filler? Thanks.

In memory of
Sounds like moisture has caused an issue. Have you fixed the cause of the peeling?
It's an apartment window sill. It has been rained on for about 17 yrs on many occasions since the apartment was renovated by a contractor. It is my guess that the issue is from the rain. I have already scraped off loose pieces, peeled the loose paints, already applied some wood filler, and realized I need a lot more. It does not good like a pro work. I am thinking of flattening the surface with filler, sand it smooth, and paint it. What do you think? Thanks.

Post a picture or two.
I like a polyester resin product used for car repairs called (Bondo) for stuff like that. Auto parts stores or even Walmart sell it. it comes in quart cans and you use a liquid hardener. Put a glob about the size of a golf ball on a coffee can lid and then add a line of the hardner maybe an inch long, mix it up good and spread it on. It will start to get hot and hard in about 5 minutes so work quick. Sand and prime and paint. Seal the can up and the unused will keep for years.
