I am about to order some Fiber Cement Siding (Hardiplank) to reside someone's addition and subsequently to reside the original asbestos siding on other parts of their home (it's part masonry, part siding). The James Hardie Web site touts something called ColorPlus, where they ship siding to you with color applied at the factory. Does anyone know if there are advantages to this vs. just ordering the Hardiplank pre-primed and painting it myself? The price I'm getting quoted for the regular pre-primed siding is $8.25 per 8 1/4 inch wide (7 inch showing) x 12-foot plank. (This is the premium smooth plank, more expensive than the rough sawmill style sold at Home Despot.) I don't know what the cost is for the ColorPlus, or if it's worth it. But I am kind of curious.
