I have a hole in the siding of my home. The siding is HardiPlank fiber cement. The hole size (diameter) is that of a cable line. A cable line was run through the siding when the previous home owners lived there but the cable line is no longer there. I want to patch the hole if possible. I really do not want to replace the board. However, I have not found a product specifically made for patching fiber cement siding. I did come across an all-purpose putty Bondo but I am not sure if this will do the trick or not.
Any suggestions on what material to use would be greatly appreciated!
