Hi I am going to use this panel http://www.homedepot.ca/product/lp-s...c-panel/935905 which exterior grade paint do you recommend to protect the siding from winter moisture from inside the house collecting on the back side of the new siding. I basically want to paint the back side of the new siding with an exterior grade paint just to protect it from any moisture that may collect during the cold winter months. Should I paint the plywood too? just to protect them .. just in case. Thanks.

Leza needs to get her terminology correct. What she calls "plywood" on the existing house is not plywood, it is OSB or particle board from what her potos show. If she asks at Home Depot or any hardware store about painting plywood, that may get her a different answer than if she asks about painting OSB.
