exterior prep on compressed clapboards

Nail holes and seams need to be filled with some type of expandable epoxy thats paintable and will not shrink. Anyone with any suggestions?

IT is like regular clapboards not wood or hardy plank it is like made of compressed fiber to look like clapboards. Its horrilble stuff knicks easy also moves with the weather thats why I'am looking for a filler that is flexible and easy to use.

Ahh, OK.
Try the gel epoxy from ART:

It sets reliably fast, and is a paintable flexible gel rather than a solid putty. It would be tough to remove any excess from a textured finished surface w/o damage. I'd say you probably have to apply before primer to avoid it flashing through the finish paint.
We use it quite often in restoration. Downside is it's not cheap, but it should never break down or come loose.
