I used the 3M filler product to make some repairs, but I have not painted over them because I am planning on having the entire boat professionally painted next season. Is this stuff OK if left unpainted?

Bondo is pourous. At least put some primer on it until it gets painted.

Would not hurt to put some primer over it. is it above or below the waterline. A quick search with google says it can be used to make water tight repairs below the water line. I think you would not have to worry about it. I know when i wet sand the materal it does not seem to me it will absorb water.

3M makes high quality stuff. If the packing says it is water tight, I would believe it.
