I am replacing all of the old, rotten siding on my 1895 Victorian with new cedar siding that I plan to prime and paint (either 6" or 8", about 4k sq.ft). Looking at the options in my area (Indianapolis, IN) I'm struggling with the choices. I found pre-primed 1/2", beveled cedar at one location vs unprimed, Grade-A. At another store, they have 5/4" (0.828"), rabbeted, unprimed select knotty, and 3/4" (0.688"), rabbeted, unprimed--the thicker, rabbeted almost doubles the price.
1) I've read you still have to prime the pre-primed, so I'm thinking any extra cost for pre-primed isn't worth it.
2) Can rabbeting pose any problems with expansion/shrink cycles?
3) For double the cost, is the 3/4 vs 5/4 thickness (less than 0.15" real difference) actually worth it?
4) I'm not so concerned about the "look"--is the Grade A vs Select Knotty very different in sturdiness/reliability? Thanks in advance!
