filler for foam?

[Scary Godmother]

I'm sure there must be a thread on this already, but I could not find it. I am glueing together two pieces of foam, I want to fill in the gap between them to make it look like one piece before I paint it. What is the easiest and/or best thing to use. I assume I will probably have to sand it a bit also to make the edges even. Any suggestions? Thanks!:devil:

I used cheap window chaulking and a plastic puddy knife on my pilars.

Wood putty works well and I have also used Bondo. The putty was easier for me to work with

Never tried the wood putty, I always used bondo. I like the way it sands down.

I used Carpenter's wood putty, let it dry, then sanded it down and did a second pass with a very thin coating of joint compound to fill in sanding marks, small dings, etc. Sand a second time, it sands quick and easy. Makes a lot of dust so do it outside.

I just built some new entry columns and put them up in the front yard. I'll take pictures today and again after dark and post.
