Basement interior windows - best caulk to use?

Hey everyone,

I purchased a bungalow last year and I am finally getting around to fixing up the basement. The previous owners look like they did a crappy job patching up the cracks on the interior side of the basement windows. Well, maybe I shouldn't say crappy.

My plan is to properly caulk the interior of the window frame, and then paint it. I have no idea what type of sealer or caulk the previous owners used. It looks clear, and in some parts, it looks as if some paint or dust got dried into it.

Some questions:

1) What type of caulking do you suggest I use? I did some research and I'm leaning toward GE Silicone II.
2) Can I paint over the caulk/sealer that the previous owners used?
3) Any other pieces of advice/suggestions before I get started?

Here are the pictures of one of the windows in the basement. They all look pretty much the same....

Any help would be greatly appreciated!

If you want to paint it, you cannot use your standard silicones and silicone is not usually the preferred sealant of most window installers.

On the interior side of things, your requirements are less arduous because it should not be exposed to weather or as much of the UV degradation.

That caulking job there is a bit of a hot mess.

You are going to spend a decent amount of time cleaning that off and if you are keeping those wood jambs, probably better suited to just rip off those old stops and try to clean the window.

If you are painting it white, I would just pull off that old interior stop and install a large enough one to cover the old caulking and paint it. Seal any gaps prior to installing the stop with caulking and/or combination of foam.
Not much of anything will stick to silicone without some undertaking. Easiest thing to do is to just clean and scrape off that old material (be careful with the window frame and look for something like a plastic razor blade), seal the gap and paint.
